THIMPHU, February 13, 2026: UNICEF today handed over Nu 18 million (USD 199,711) worth of lead testing equipment to the Ministry of Health, advancing Bhutan’s vision of a Lead-Free Bhutan.

This contribution builds on Bhutan’s reaffirmation at UNICEF’s high-level side event “Toward a Lead-Free Future” during the 80th UN General Assembly in 2025, where Prime Minister Tshering Tobgay called for urgent global action to end childhood lead poisoning. Translating global commitments into national action, the equipment strengthens Bhutan’s capacity for lead surveillance, environmental testing, and frontline health service delivery.

The new equipment will enhance environmental and product testing, generate reliable data, and monitor compliance with safety standards. Appreciating the Royal Government of Bhutan and the Ministry of Health’s leadership in generating evidence through the first-ever National Blood Lead Level Survey, UNICEF Bhutan Representative Rushnan Murtaza reaffirmed UNICEF’s commitment to protecting children from environmental health risks and strengthening systems for a safer future.

“UNICEF is confident that this support will strengthen investigations to build strong systems to protect children through evidence-based policies, effective regulations, and sustainable surveillance,” said Rushnan Murtaza. “This handover is a step towards our shared vision of a Lead-Free Bhutan.”

Health Secretary Pemba Wangchuk thanked UNICEF for the continued support towards protecting the health of women and children, assuring that the new set of equipment will strengthen surveillance on lead exposure.

The equipment set includes three XRF analyzers for swift detection of lead in paint, soil, dust, and consumer goods; five Lead Care II analyzers for rapid, cost-effective blood-lead testing with on‑site results; four Rad-67 pulse oximeters for non-invasive monitoring of hemoglobin levels in children and pregnant women; and reagents and consumables for ongoing monitoring. All equipment are verified, recorded, and packed for safe use in accordance with WHO pre-qualification standards.

Trust but Verify: A Webinar Recap on Geochemistry and Alloy Analysis

Tue, 25 Nov 2025 06:16:27 GMT

In a recent webinar hosted by Simon Nordstad, CEO and Founder of myStandards GmbH, participants were treated to a comprehensive overview of analytical techniques, sample preparation strategies, the importance of reference materials, and essential QA/QC concepts relevant to geochemistry and alloy analysis. Here’s a recap of the key insights shared during this engaging session.

Understanding the Analytical Techniques

Comparison of four key analytical methods:

ICP-MS (Inductively Coupled Plasma Mass Spectrometry)
ICP-OES (Optical Emission Spectroscopy)
LIBS (Laser-Induced Breakdown Spectroscopy)
XRF (X-ray Fluorescence)

No single technique is universally superior—each serves different analytical needs depending on the elements of interest and required sensitivity.

Sample Preparation: Why It Matters

Sample preparation plays a critical role in achieving accurate and reliable results—especially for XRF. The webinar outlined common prep methods:

Loose powders in sample cups or bags
Pressed pellets, with or without binders
Fused beads, typically for lab-based analysis
Flat metal surfaces for alloy testing

While minimal prep can suffice for handheld XRF, investing in better preparation—like using pressed pellets—can significantly improve data quality.

Vanta Max XRF analyzer analyzes a soil sample in the field.

Reference Materials and Calibration

The session also covered the distinctions between Reference Materials (RMs) and Certified Reference Materials (CRMs). According to ISO standards, CRMs undergo rigorous validation procedures and come with a certificate indicating value, uncertainty, and traceability.

Advice is that the best way to ensure analytical confidence is to use materials that meet ISO 17034 accreditation or at least follow its standards transparently.

QA/QC Concepts: Accuracy and Precision

There are two cornerstone concepts of quality assurance:

Accuracy: How close a result is to the true value.
Precision: How consistent repeated measurements are.

How XRF calibration works? By plotting the counts-per-second data from the XRF spectra against known concentrations from reference materials, analysts can build reliable regression models.

The Matrix Effect: Why Calibration Must Match Your Material

Not all samples behave the same during analysis. The “matrix effect” refers to how the overall composition of a sample (its matrix) can influence the analytical results—even when the elemental concentration remains the same.

The solution? Matrix-matched calibrations. Your calibration should be based on samples of the same type as you intend to measure.

Sample Prep Matters—Even for the Same Sample

Sample preparation directly affects the output of XRF analysis. Consistency is key: your samples must be prepped in the same way as your calibration standards to maintain accuracy.

Quality Assurance vs. Quality Control: A Quick Breakdown

There is a clear distinction between QA and QC:

QA (Quality Assurance): A proactive, process-based strategy to prevent defects. It sets your quality goals.
QC (Quality Control): A reactive, product-based method to detect and correct errors. It verifies your results.

In XRF, this means ensuring your device consistently provides accurate results by monitoring those results over time.

Field-Proven QA/QC Practices

To ensure long-term precision you should monitor performance of your instrument. A few methods for this are:

Sample bracketing: Insert known standards between sets of sample measurements.
Cross-validation: Compare results from XRF with other techniques like ICP-MS.
Repeatability checks: For example, measuring the same pressed pellet 100 times showed less than 1% relative deviation—an excellent indication of precision.

Defining Control Limits

Evident’s handheld XRF instruments help users verify results in real-time. For example, alloy verification specifications for many alloys are built into the analyzer, comparing elemental ranges to spec automatically. Additionally, by running repeat tests on a single sample, users can determine their instrument’s inherent precision and set custom control limits.

Trust the Machine—But Always Verify

A handheld XRF analyzer is only as accurate as its calibration and usage allow. It’s not a “point-and-shoot” solution—matching samples to the correct calibration and applying strong QA/QC practices is essential. Otherwise, precise-looking results may still lead to costly mistakes.

“You can trust the machine to give you the same number repeatedly—but whether that number is right? That’s on you.”

Want to learn more? Watch the full webinar replay to explore all the tools and techniques discussed and gain confidence in your XRF results—no matter the matrix.

Whether you're working in mining, metallurgy, or material science, this webinar reinforced the importance of choosing the right technique, preparing your samples with care, and validating your results with trustworthy reference materials.

If you missed the live session, be sure to tune in for a deeper dive into the science behind the methods and best practices that drive analytical confidence in solid-state geochemical and alloy analysis.

Striking a balance between handheld XRF and lab-based methods

Mon, 20 Oct 2025 06:38:13 GMT

Africa’s growing role in the global resource economy continues to drive the demand for efficient and reliable testing methods. X-ray fluorescence (XRF) technology, which has served the mining industry for decades, remains a critical tool, offering rapid, non-destructive elemental analysis in the field.

Jonathan Pearn, Regional Technical Cargo Specialist at Alfred H Knight, emphasises that while XRF isn’t a new innovation, how it’s being used has evolved. “What has changed is how smart companies are integrating it into their operations,” he explains. Rather than replacing lab-based analysis, XRF should be seen as a complementary, versatile tool that adds value across the mining and minerals value chain.

Accuracy Versus Speed

Handheld XRF analysers are portable, non-destructive tools that enable near-instant elemental analysis with minimal sample preparation, making them ideal for time-sensitive applications such as on-site material assessments. These devices significantly reduce reliance on laboratory turnaround times, especially during upstream exploration, field screening, and in-transit material inspections. However, Pearn cautions against sacrificing accuracy for speed.

“If the results are to be used in a commercial transaction, export certification, or for environmental compliance, lab-based techniques such as fire assay, titration, ICP, AAS, or fused bead WDXRF are essential,” he says. These laboratory methods deliver the precision and traceability required for critical decision-making. Even with Handheld XRF, the quality of results hinges on rigorous sampling, proper preparation, and controlled measurement conditions.

The Importance of Sample Preparation

Handheld XRF results are most reliable in controlled environments. Under such conditions, businesses can extract meaningful operational insights without compromising data integrity. “The Handheld XRF is a valuable tool in logistics and cargo validation, particularly given the rise in fraud involving base metal concentrates and critical ore minerals,” Pearn explains. By enabling initial characterisation, ensuring traceability, and detecting anomalies as material moves from origin to port or processing plant, Handheld XRF enhances quality control across the supply chain.

Complementary Methods Deliver Greater Value

The real value emerges when Handheld XRF is used in conjunction with laboratory methods. For instance, it can help:

Screen incoming materials
Minimise material mix-ups
Identify quality variations early

This is particularly beneficial in high-volume operations, where even small errors can lead to costly inefficiencies or losses. “Field-based XRF remains especially useful for clients monitoring products in transit or operating in areas where sampling is difficult due to local regulations,” says Pearn.

Extracting the Most Value: Key Considerations

When determining the best approach for testing, companies should ask:

Is the material suitable for Handheld XRF?
Are operational conditions conducive to accurate results?
Has the sample been adequately prepared?

Strategic clients recognise that Handheld XRF and lab-based testing are not competing, but complementary. XRF is ideal for rapid on-site screening and decision-making, while laboratory analysis offers the precision needed for compliance and trace-level detection. Maxime Francois, the Regional General Manager further noted that, “at AHK, our clients are our top priority. We continually seek new ways to enhance our support and expand our capabilities in areas where our clients want us to be involved. In line with this commitment, we have invested in three new XRF technologies at strategic locations across Southern Africa over the past few years.” In conclusion, smart organisations optimise both efficiency and analytical confidence by combining XRF’s speed with the accuracy of lab-based methods—leveraging each for what it does best.

Out of This World! Museum Tests Meteorite Collection Using XRF

Mon, 27 Jan 2025 09:34:39 GMT

A meteorite is a fragment of a comet, asteroid, planet, or meteoroid that survived its passage through outer space and the atmosphere to land on the surface of the Earth. Unlike the fleeting beauty of meteors that illuminate the night sky as shooting stars, meteorites are enduring relics from outer space.

As samples of cosmic material, meteorites have caught the eye of numerous researchers and collectors. Researchers are interested in them because meteorites contain information about the early solar system. The study of meteorites can enrich our knowledge of how the solar system evolved.

Example meteorite collection. Image courtesy of a private meteorite museum in Shanghai, China.

3 Types of Meteorites and What They’re Made of

Meteorites are made of rock, metal, or a mixture of both. These “space rocks” have traditionally been classified into three groups: iron meteorites, stony meteorites, and stony-iron meteorites.

1. Stony meteorites

Stony meteorites are composed of mostly silicate minerals (rock-forming minerals) but also contain nickel (Ni) and iron (Fe). According to NASA, around 95% of known meteorites are stony.

2. Stony-iron meteorites

Stony-iron meteorites are very rare. According to NASA, less than 2% of meteorites are the stony-iron type. Its composition is almost equal parts metal and silicate material. The metal part is a mixture of iron (Fe) and nickel (Ni).

3. Iron meteorites

Iron meteorites are almost entirely metal. They are mostly composed of iron (Fe) and nickel (Ni), and their dense, metallic nature makes them easier to identify among Earth rocks. As a result, iron meteorites are more common in collections despite the small percentage that fall to Earth.

Different types of meteorites. From left to right: stony meteorite, iron meteorite, and stony-iron meteorite. Images courtesy of a private meteorite museum in Shanghai, China.

Space or Earth Rock? Museum Tests Meteorites with XRF to Find Out

For meteorite hunters and collectors, it’s important to know if the rock is a real meteorite when searching for them in the field or planning to purchase a suspected meteorite.

Since the chemical compositions of known meteorites are well studied, handheld X-ray fluorescence (XRF) analyzers can help experts sort fake meteorites by looking at their chemical composition. These portable devices can instantly identify the elements and the amount of each element in a sample, making them convenient tools for testing meteorites outside in the field or indoors in a museum.

As an example, researchers from one meteorite museum in China used our Vanta Element-S handheld XRF analyzer with Alloy Plus to understand the full chemistry of their meteorite collection. They analyzed the rocks to test for iron (Fe), nickel (Ni), aluminum (Al), sulfur (S), and phosphorus (P), which enabled them to quickly identify fake meteorites in their collection.

Notably, the Vanta Element-S analyzer offers quick analysis of the metallic elements in the meteorite and can analyze light elements, including Al, S, and P.

Innov-X Africa take steps to avoid load shedding

Thu, 16 Nov 2023 07:26:08 GMT

“There has been plenty written and spoken about Eskom and load shedding in South Africa and sadly the situation is not getting better in any way at all. The situation has had some sort of effect on every single South African and those that visit our country. One of the few positives to come out of the debacle is the growth in the industry of the manufacturers, suppliers and service providers that provide solutions for keeping the power on so that homes and businesses can continue to function. It is almost like the security industry in South Africa – industries have been created for all the wrong reasons,” said Stuart Bateman, Managing Member of Innov-X Africa.

“Another outcome is that it has accelerated the move into green energy where many are using the sun to keep the lights on. South Africa’s power supply issues go as far back as 2007. They are not a new phenomenon – they just got worse.”

“Energy security – not just electricity supply – threatens the sovereignty of the country. Shortages of liquid fuels, oil and gas are also proving to be big challenges for South Africa. Due to other problems in the world, importing liquid fuels is not sustainable. In addition, some of the country’s big refineries will soon shut down to avoid costly refurbishments and upgrades to comply with the latest environmental legislation and stipulated minimum emissions standards. These developments are not helping the country.”

“For the current energy challenges, South Africa must respond and adopt similar disaster-management strategies as those used to deal with the Covid-19 pandemic. It is time to acknowledge that we have gone past the crisis stage in our energy challenges and we are now in a state of energency.”

“At least there are now schedules of when the power will be turned off in your area and you can organise your life and business around these times. But it does not help if you are off for 10 hours in a day.”

“We – Innov-X Africa – like everybody else, have had to take steps to avoid load shedding ruining our business and have decided to move from the office complex in Bedfordview, where we have been located for 13 years, to First Avenue, Dunvegan, which is a suburb that is part of Edenvale, Gauteng.”

“We are very pleased that we have made the move because besides investing in a PV solar system and inverter battery that keeps the power on all the time while we are in the office, there are other benefits built-in for our business.”

“The new premises are much larger. We have gone from approximately 170m² space to 320m². This gives us the opportunity to setup a professional demo lab that we can also use as a training centre. We are centrally situated so our access from all the industrial areas is relatively easy.”

“Of course it also gives more space to increase staff numbers without being on top of each other.”

“Innov-X Africa has now been in business for 16 years as the sole distributors for Evident Olympus XRF and XRD equipment and Belec optical emission spectrometers for metal analysis in Sub-Saharan Africa. We supply desktop, portable and handheld XRF analysers of the highest quality and most robust into various industries, such as mining and exploration, alloy and steel, precious metals, recycling and many more.”

“We have direct access into these two expert companies in the field of material determination of metals. Applications include foundry metal input, scrap metal recycling, catalytic converter analysis,

geochemical analysis, precious metals analysis, positive material identification and catalytic converter recycling, to name a few.”

“Other applications include screening for lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg), chromium (Cr), and other toxic metals in consumer products such as toys and apparel, to comply with regulations.”

Increased interest in XRF, OES from steel sector

Thu, 27 Jul 2023 08:04:31 GMT

Portable X-ray fluorescence ( XRF ) and Optical Emission Spectroscopy (OES) equipment provider Innov-X-Africa has noted increased interest in its products from the steel sector, with salesperson Craig Bateman observing that the primary applications are for quality control and scarp sorting applications.

Innov-X-Africa , which is affiliated with the South Africa Stainless Steel Development Association (SASSDA) and the South African Institute of Foundrymen, has, in recent months, delivered two XRF analysers to a stainless-steel producer and had worked with a local steel manufacturer in the past, delivering both OES equipment to the manufacturer’s site.

Bateman explains that the XRF differentiates between grades of alloys, which is why it has become popular for scarp sorting applications. “Our customer does a lot of stainless-steel scrap purchasing, and it must be sorted as different grades of stainless steel have different chemical compositions.”

He explains that different grades have varying amounts of chrome, nickel, molybdenum and other valuable elements, and that the incoming scrap must be sorted according to its composition before it is sent to the smelter.

Thereafter, the customer can also use an OES to check the melt, looking for impurities and individual elements at a much lower concentration. “In the actual melt, for example, they wouldn’t want the phosphorus or sulphur concentrations to be low.”

Bateman notes that, a trend over the last year is that, because of the high price of steel and steel products locally, largely owing to high input costs, manufacturers have increased imports for steel and stainless steel, which, in turn, has raised some concerns about quality.

“What’s happening is that, in certain instances, companies are using certificates that state that the product they’ve provided is, for example, 316 grade stainless steel, but because of the high commodity prices, they might have only used the bare minimum of chrome in the production process. So that's where we've seen customers in the manufacturing sector introduce OES and XRF to do a form of grade and quality control to ensure that the steel grade that they have received matches the grade they bought.”

He comments that this is important as, in addition to local manufacturers getting their money’s worth, there is also a reputational risk to using poor quality, or incorrectly labelled products as inputs in their processes.

“They're processing and machining these steels and then sending finished goods to their customer that are sometimes intended for highly specialised applications. If one looks at stainless steel grade 316 and compare it with 304, there is a massive difference, both in terms of price and application. 316 is known for its corrosion resistance, and would therefore last longer in a coastal application, whereas the use of 304, in the same application, might result in a critical failure.”

Bateman adds that the difference in expected and delivered grade quality need not necessarily be a result of unscrupulous companies looking to cut costs, it may also be a case of human error. Regardless of whether the grade discrepancy is intentional, instituting a measure of quality control using XRF and OES can help manufacturers reduce the risk of using poor quality inputs in their processes.

Out with the Old

Bateman explains that portable XRF and OES have numerous benefits.

“Historically, if you have incoming material, employees would have had to cut off a piece and then send it to the laboratory for testing, which tended to be a time-consuming process. And obviously, this also had a higher chance of human error –, mislabelling, sample contamination. There’s also the possibility of poor calibrated lab equipment.”

With XRF and OES, the systems are calibrated internationally, to ensure they meet international standards, before they are delivered to Innov-X-Africa and, therefore, well before they reach the customer. Moreover, the XRF and/or OES equipment can be used on site, and produce results within minutes, depending on the type of sample and the depth of analysis in terms of concentrations, with lower concentrations taking longer.

In terms of limitations, Bateman notes that, certain entry-level XRF equipment is limited in terms of the number of elements it can detect, as well as the range of concentration.

He stresses, however, that the degree of detection depends on the application and the element, as different elements will have different ranges depending on how heavy they are, as well as other properties.

An Eye on the Future

Bateman notes that Innov-X-Africa recently moved to a new premises, as part of its push to expand and improve its overall longevity.

The company has been active in mining throughout sub-Saharan Africa but is looking to increase its footprint in other sectors, such as steel.

“I'm chatting to existing steel producers and foundries and looking to introduce them to all the instrumentation that will hopefully be replacing some of their outdated equipment soon. We want to increase our service and our impact on the South African market, and in sub-Saharan Africa more broadly.

“Our primary focus right now for sub-Saharan Africa is still the Geochem sector , because of the amount of exploration currently taking place for critical minerals and battery metals. I'm sure that, within the next few years, we’ll see more activity in other sectors, and we’ll be there when it happens,” Bateman concludes.

Carbon Steel Success—How XRF Helped ID an Ancient Helmet

Mon, 06 Feb 2023 07:00:03 GMT

Our Vanta™ handheld XRF analyzer was recently featured on an episode of the popular History Channel TV show Pawn Stars. In the show, people bring items into the shop to potentially sell, trade, or pawn. Often, people don’t have a lot of information about the items that they’re bringing in. To determine a fair price, outside expertise can be required to get more information. That’s where a tool like the Vanta analyzer can help.

On this episode, a customer brought in a helmet that they thought was made of iron. An expert was able to confirm that the piece was an authentic Anglo-Saxon helmet that was about 1500 years old. The helmet was in excellent condition, making it a rare find. Typically, iron breaks down in the presence of oxygen, so the helmet likely ended up in a low-oxygen environment, such as a bog or river.

It was important to know the helmet’s material chemistry, as the Anglo Saxons worked in iron and carbon steel. An expert used a Vanta analyzer to test the helmet using X-ray fluorescence to determine its elemental composition.

n just a few seconds, the Vanta analyzer confirmed that the helmet was made of carbon steel.

The screenshot below shows the analyzer obtained an exact grade match. The helmet was made from 99.76% iron with traces of copper (Cu), zinc (Zn), chromium (Cr), etc.

An Anglo Saxon helmet of this age and quality is truly a rare find.

UNDERSTANDING X-RAY FLUORESCENCE: HOW DOES XRF WORK?

Wed, 21 Dec 2022 08:00:00 GMT

Energy dispersive X-ray fluorescence (EDXRF), commonly referred to as XRF, is a fast, nondestructive method to measure the elemental composition of a material. But how does it work?

Here, we will discuss the science behind XRF and explain how it works in handheld analyzers.

The Science Behind Energy Dispersive XRF

X-ray energy forms the basis for insightful measurement techniques. Energy dispersive X-ray fluorescence identifies metals and elements in an object by detecting their signature XRF emission energies.

Here’s a detailed explanation of the process:

Essentially, all elements have a fixed number of electrons arranged in atomic orbitals around their nuclei. When photons from the X-ray tube strike the object of interest with enough energy to expel the electrons out of the elements’ innermost orbitals, the atoms become unstable.

To regain stability, electrons from the outer orbitals move into the newly vacant spaces in the inner orbitals. As an electron transitions from an outer orbital to an inner orbital, it emits photon energy known as X-ray fluorescence. This release of energy is illustrated in the image below.

This energy is determined by the different energies between the initial and final orbitals of the individual’s electron transitions.

The amount of element present in an object is determined by the intensity of the signal detected at its signature energy. For example, if lead (Pb) is present in an object, an XRF signal will be detected at 10.55 and 12.61 keV, and its quantity can be determined by plotting the energy (E) vs. intensity (I).

How Handheld XRF Works

Now that you understand the science behind XRF, you might be wondering how this technology works in handheld XRF analyzers like our popular Vanta™ series .

The handheld XRF process can be broken down into four simple steps:

1. Emission

First, the analyzer emits X-rays.

2. Excitation

The X-rays hit the sample, causing it to fluoresce and send X-rays back to the analyzer.

3. Measurement

The detector measures the energy spectrum. This tells you which elements are present and the amount of each element present. It’s important to note that Olympus XRF can’t be used to measure every element in the periodic table. In general, our analyzers can measure from phosphorus to plutonium (P–Pu) on the periodic table of elements.

4. Results

Olympus Axon Technology™ processes the energy spectrum and displays the sample’s elemental composition. For metals, we match the composition to a particular grade.

How Can These XRF Results Be Used?

XRF analyzers do complicated math so you can focus on getting fast, accurate results when and where you need it. You can use these fast elemental analysis and alloy identification results for a wide range of purposes. Common XRF applications include:

Material verification
Scrap recycling
Mining and geochemistry
Environmental assessments
Education
Regulatory and safety screening
Precious metals analysis

SASSDA GOLF DAY

Tue, 06 Dec 2022 07:22:24 GMT

The day commenced with us setting up our gazebo, table, banners, drinks and Vanta Handheld XRF analyser.

Our first group came through to 17 ^th hole that we had set up for the longest drive for a prize of our signature golf balls.

We have some fantastic tee offs on the day and some not so fantastic.

As a networking event for us as Innov-X Africa the SASSDA Bryanston golf day was very productive to be out and meet with the people in the industry that are in need of our analysers.

We had a chance to show off our Vanta handheld XRF analyser, as well as some of its capabilities.

Vanta analysers are important tools in a material verification program for new and existing assets within a plant or refinery. From verifying incoming material to final confirmation at the point of installation, Vanta analysers provide essential asset integrity information to help prevent catastrophic or unplanned maintenance events and increase asset life expectancy. In short, the capabilities are:

Confirm the material of construction
Verify material against mill certificates and material test reports
Identify non-traceable or improperly marked material

Vanta analysers are the ideal tools to verify the chemical composition and grade of welds. The optional 3 mm aiming camera enables an inspector to accurately analyse thin weld beads independent of base material as well as other conjoined metals, alloys, and small fixture components, such as wires and solders. An optional panoramic camera saves images along with the analysis results for archiving and reporting.

This Revolutionary analyser has Every circuit, contour, and interface of is engineered to be the best of its kind. Vanta analysers incorporate the new Axon Technology™, a breakthrough in XRF signal processing that delivers accurate and repeatable test data and ensures inspectors get alloy chemistry and grade ID in 1–2 seconds for typical plant and refinery applications. Axon Technology uses ultra-low-noise electronics that facilitate higher X-ray counts per second and faster results. Coupled with a quad-core processor, Axon Technology makes Vanta analysers remarkably responsive, pushing the limits of performance so you get the best results in the least amount of time. Axon Technology provides test-to-test and instrument-to-instrument repeatability. Whether it’s your first test on your first analyser or your thousandth test with your hundredth analyser, the Vanta handheld XRF gives you the same result every time.

Vanta analysers accurately and repeatably detect and quantify:

Residual Elements (RE) in low alloy and carbon steels

Trace silicon (Si) in carbon steel per API RP 939-C

Sulphur (S) and phosphorus (P) for in-service stainless steels

As a consumer, it can be difficult to understand the complexities surrounding the different X-ray fluorescence (XRF) analysers on the market. XRF analytical specifications can be confusing—for instance, you may have heard people talk about count rate, resolution, voltage, and tube watts, but you’re not sure of their significance. While these features all influence the price and performance of a handheld XRF analyzer , what is most important is how they work together to achieve your objectives, without breaking the bank.

What Does an XRF Analyzer Cost? The only way to truly evaluate if an instrument is a good fit for your needs—and worth the investment—is to look at the results it provides for the elements you’re trying to measure. We’ve outlined some of the factors that influence the price and performance of a handheld XRF analyser : X-Ray Fluorescence Analyzer Detector Types: PIN or SDD There are two types of detectors used in handheld XRF analysers : PIN and SDD. PIN detectors are an older technology that is less expensive, but also less sensitive than a silicon drift detector (SDD). Your answers to the three questions below will help you determine if you need the sensitivity of an SDD.

Do I need to measure light elements? In XRF lingo, light elements are magnesium, aluminium, silicon, phosphorous, and sulphur. If you need to know the concentration of these elements, then you need an SDD.
Is testing speed important? An SDD can identify most alloys in a second or two. A PIN instrument can take 8 to 10 seconds to perform the same task. If you are testing many samples, the analysis time can add up, making the SDD instrument the cost-effective choice.

All these factors can affect the price of a handheld XRF analyzer package. The key is to choose an analyzer with the exact performance and features you require.

THE POSITIVES OF USING PORTABLE XRF FOR ELECTRONICS AND BATTERY RECYCLING

Wed, 09 Nov 2022 10:48:42 GMT

Olympus’ Damien Blondel recently presented at the International WEEE and Battery Recycling Virtual Conference , an event that brings together industry professionals from across the world to discuss trends, insights, and best practices in the electronics and battery recycling industry.

Damien reviewed why portable X-ray fluorescence (pXRF) is a powerful technique to get on-site, fast, and easy chemical composition of a wide range of materials in electronics and battery recycling. If you missed the presentation or want a recap, this post will share highlights and lessons from the talk.

The Positive Benefits of Portable XRF for Electronics and Battery Metals Recycling

Portable XRF is a versatile tool for waste electrical and electronic equipment (WEEE) and battery recycling, including:

Battery metals identification and quantification
RoHS compliance testing
Precious metals testing in electronics

Let’s explore each XRF application for battery metals recycling.

I dentifying and Quantifying Battery Metals

pXRF analyzers provide key battery commodity concentrations for these elements:

Cobalt (Co)
Nickel (Ni)
Manganese (Mn)
Copper (Cu)
Aluminum (Al)
Rare-earth elements (REEs)

pXRF instruments such as our Vanta™ handheld XRF analyzers can help optimize the extraction, smelting, and refining processes, as well as reduce the number of lab tests. While pXRF analyzers can’t quantify lithium (Li), portable X-ray diffraction (pXRD) tools such as our BTX™ III or TERRA™ II instruments can complement pXRF and analyze lithium and other key materials in battery metals recycling or battery metal exploration.

RoHS Testing: Screening for Toxic Metals

pXRF analyzers can also screen for toxic metals in many consumer products, including electronics, enabling RoHS compliance.

Screening for toxic metals with the Vanta handheld XRF analyzer

For instance, the Vanta analyzer can screen for:

Lead (Pb)
Cadmium (Cd)
Arsenic (As)

ACCURACY VS. PRECISION IN HANDHELD XRF: WHAT'S THE DIFFERENCE?

Wed, 09 Nov 2022 08:00:00 GMT

When evaluating analytical results with handheld X-ray fluorescence (XRF) , it’s important to understand the difference between accuracy and precision.

Precision is a measure of repeatability, or how much one test result is like another. Accuracy, on the other hand, is whether that result hits the target. Of course, for any analytical technique, you want both good precision and good accuracy.

Keep reading to learn more about accuracy and precision in handheld XRF analyzers.

Understanding Precision

Vanta™ handheld XRF analyzers report the precision (known mathematically as sigma) in the +/- column on the display. Precision is mostly a function of the number of X-ray counts. You can test longer to get more counts and improve the precision. Or, you can use an analyzer with a higher count rate (such as a silicon drift X-ray detector instead of a PIN detector).

In this test result for stainless steel 321, the Vanta XRF analyzer calculates results with 2 sigma.

Understanding Accuracy

To change the accuracy of a result, the calibration needs to be adjusted. Olympus offers User Factors in most methods to adjust the average result value. We recommend that you analyze several certified reference samples or samples tested by a reliable laboratory with the Vanta analyzer and determine a trend before factors are adjusted. Adjusting to a single point is risky.

Understanding Reproducibility

Finally, as an instrument maker, we work hard to make each analyzer for a given model just like the next to help ensure reproducibility. High reproducibility helps us ensure that data can be trusted no matter which model you use. This means that if you test the same sample with two different Vanta analyzers, you’ll still get the exact same result.

High reproducibility helps ensure that data from your Vanta XRF analyzer is consistent from test to test, and analyzer to analyzer.

Cutting Through the Noise—Get All the Facts about XRF

XRF technology can be challenging to understand, and misinformation about XRF analysis can make it difficult to decide which instrument is right for your application. To make the best choice, it’s important to get all the facts about XRF.

Learn more about the science behind XRF in our exclusive e-book, Cutting Through the Noise. It reviews the basics of XRF and clears up common misconceptions about the technology.

HEAVY METALS IN WASTEWATER: LOCATING POLLUTION SOURCES USING PORTABLE XRF

Wed, 26 Oct 2022 08:00:06 GMT

Heavy metal pollution in wastewater from industrial activities is a significant environmental issue. Discharging untreated wastewater that contains heavy metals into the environment can contaminate aquatic life and agricultural crops. Heavy metals can then enter the food chain, be absorbed through the human body, and potentially cause serious health issues due to their toxicity.

Sources of industrial wastewater containing heavy metals include:

Electric power plants
Metal surface treatment
Electroplating
Electronics manufacturing
Organic chemicals manufacturing
Iron and steel industry
Mines and quarries

Finding a Rapid Method to Detect Heavy Metals Pollution in Wastewater

The ability to quickly detect heavy metal pollution in wastewater and locate its source are critical for environmental monitoring and protection. To locate and address point source pollution, monitoring agencies need a robust, versatile, and rapid analytical method to identify and detect the presence of heavy metal contaminants in wastewater. Modern analytical instruments such as portable X-ray fluorescence (pXRF) analyzers can empower agencies to detect, locate, and address sources of wastewater contamination swiftly and accurately.

For example, the Vanta™ handheld XRF analyzer is a versatile environmental monitoring solution with the following capabilities:

Accurate elemental analysis: Analyzes more than 20 elements, including the heavy metals chromium (Cr), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), cadium (Cd), mercury (Hg), and lead (Pb)
Fast results: Provides immediate qualitative and quantitative information in real time
Field ready: Lightweight, portable, and rugged for fieldwork conditions
Nondestructive: Chemical analysis method that doesn't damage the sample
Productive: User-friendly interface makes the device easy to use with minimal training
Economical: Affordable and low cost of ownership

Despite these benefits, pXRF analyzers face some challenges for heavy metal testing in wastewater. First, these devices are typically calibrated for use on solid materials such as soil. Second, the limit of detection (LOD) is only in the single-digit parts per million (ppm) range. More expensive and time-consuming laboratory methods, such as atomic absorption spectrometry (AAS) or inductively coupled plasma (ICP), can measure parts per billion (ppb) levels.

The Solution: Combining Time-Lapse Ion Exchange Resin Sachets and Portable XRF

To overcome these challenges, time-lapse ion exchange resin sachets (TIERS) can be combined with pXRF testing to optimize the analysis of heavy metals in wastewater. A time-lapse ion exchange resin sachet is a non-woven bag that contains resins that adsorb metals over time. The bag is placed in a body of water (e.g., the water surrounding discharge pipeline outlets at a factory) for seven days as the resins accumulate heavy metals. After the seven-day monitoring period, the TIERS is tested using a pXRF analyzer.

Time-lapse ion exchange resin sachets help optimize XRF analysis of wastewater in several ways:

Lower limits of detection: Amplifies analytes up to 1000 times; the concentration factor increases sensitivity and reduces matrix effects
Higher precision: Sachets effectively provide a time average over the seven-day deployment to account for variable discharge concentration and volume
Real-time field mapping: Customizable qualitative and quantitative data tagged to each area is analyzed for easier, more comprehensive interpretation of results

The Importance of Portable XRF in Environmental Monitoring

A fast, reliable, and inexpensive field-based monitoring system enables regulators to work their way upstream to locate problematic discharges. TIERS consistently monitor a location for an entire week to identify even intermittent problems. As industries continue to expand water use rapidly, nearby water user groups are increasingly looking for confidence that regulations are being met. Cases of non-compliance are increasingly difficult to identify without real-time monitoring. Modern analytical solutions such as portable XRF can help streamline and expedite extensive testing processes, helping agencies save resources and promptly resolve environmental health hazards.

THE ROLE OF XRF ANALYZERS IN AUTOMOTIVE CATALYST RECYCLING

Mon, 17 Oct 2022 08:51:17 GMT

Handheld XRF analyzers play a major role in the recycling of automotive catalysts.

To understand how XRF analyzers fit into automotive catalyst recycling, it is necessary to start with a brief description of the automotive catalytic converter (also called an automotive catalyst, car catalyst, or car cat) and its function.

In short, the purpose of an automotive catalytic converter is to reduce the pollutants emitted into the atmosphere from vehicle exhaust. It does so by using a catalyst (a substrate that accelerates a chemical reaction) to turn harmful gases from the exhaust system into less polluting ones.

A car catalyst is a honeycomb cylinder coated with a layer of platinum (Pt), palladium (Pd), and rhodium (Rh)—also known as platinum group metals (PGMs). Unburned residues in the vehicle exhaust, such as carbon monoxide (CO), hydrocarbons (CH), or nitrogen oxides (NO), pass through the honeycomb cylinders coated with PGMs and are oxidized and neutralized by oxygen in the exhaust gas.

What’s driving the recycling of automotive catalysts?

Automotive catalysts have become an indispensable part of internal combustion engine vehicles. The average life of an automotive catalyst depends on several factors, such as fuel quality and engine cylinder volume. It usually has a service life of 100,000 km (about 62,000 miles).

With proper treatment of automotive catalysts, we can provide a second life for the PGMs in them. By properly sorting and processing spent catalysts, the PGMs can be recycled and reused in future production. Further, recycling automotive catalysts is both economically profitable and important to meet environmental standards.

Platinum and palladium are two of the most effective elements in the neutralization of noxious emissions. While platinum and palladium are used in industries besides automotive manufacturing (e.g., jewelry production), most platinum and palladium produced today are used to make automotive catalysts.

With the adoption of emission and fuel standards (China VI, Tier 3, Euro 6d, and Bharat Stage VI), the demand for PGMs will continue to grow and drive the recycling of automotive catalysts.

From the perspective of environmental protection, recycling used automotive catalysts is much less hazardous than extracting platinum group metals through mining. Further, palladium is generally a by-product of mineral processing plants, and its extraction is very inefficient.

How does handheld XRF assist in the recycling of automotive catalysts?

Without special equipment, it’s impossible to quickly determine the amount of PGMs in automotive catalysts—causing a roadblock to the PGM recovery process. This is where X-ray fluorescence (XRF) testing comes in. XRF is a proven analytical method used in the recovery of automotive catalysts.

Many recyclers rely on portable XRF devices for a fast and simple car catalyst analysis. Our Vanta™ handheld XRF analyzer can provide the amounts of platinum, rhodium, and palladium in catalyst in seconds.

Vanta handheld XRF analyzers

The Vanta analyzer can also analyze elements ranging from magnesium (Mg) to uranium (U) (in the order of the Periodic Table of Elements), displaying up to 45 elements. Elements of interest for the recycling of automobile catalysts include:

Platinum (Pt)
Palladium (Pd)
Rhodium (Rh)
Tantalum (Ta)
erium (Ce)
Selenium (Se)
Tungsten (W)
Silicon (Si)
Lead (Pb)
Zirconium (Zr)
Ruthenium (Ru)
Lanthanum (La)
Nickel (Ni)
Sulfur (S)

All these elements are prioritized and included in the Vanta analyzer ’s customized car catalyst method. Of course, you can still analyze other elements from Mg to U.

Using the Vanta XRF analyzer, recyclers can categorize automotive catalysts to select an optimal extraction method for PGMs and determine a fair recovery price. The analyzer can be used in combination with grinders, blenders, and scales, making it an essential tool for recycling automotive catalysts.

The Vanta analyzer also helps prevent fraud. It detects elements that could be added to catalyst materials to falsely boost their precious metals values.

With the growth of the automotive catalyst recycling industry, the number of scammers trying to sell used automobile catalysts at the highest possible price is increasing. A common method used to falsely increase the value of automobile catalysts is adding additives containing lead (Pb). More sophisticated deception methods add tantalum (Ta) or selenium (Se) to the mixture to simulate the platinum (Pt) peak on the XRF spectrum.

Errors can also occur without malicious intent. A portable XRF device that has not been professionally calibrated can mistake tungsten (W) in diesel particulate filter (DPF) as platinum (Pt). This error is common. The Vanta analyzer can help avoid these errors and frauds thanks to its unique calibration.

How do you prepare samples from catalytic converters to get accurate and representative results?

Example of a car catalyst honeycomb lump sample (left) and preliminary surface palladium (Pd) concentration (ppm) results (right) to aid in rough sorting

Sample prep is an important part of an accurate XRF analysis. When recycling automotive catalysts, two types of samples are usually prepared: honeycomb bulk samples (whole or split) and powder samples.

PGM coatings on the honeycomb structures are often not uniformly distributed. As a result, these samples can only provide a preliminary test result to classify automotive catalysts or identify "empty automotive catalysts" where the PGMs are already removed.

To classify automotive catalysts for purification or batch production, additional steps in the sample prep process are needed to obtain representative results. In general, we recommend the following method:

Rough classification by type
Grinding by type (it is important to make the particle size distribution as uniform as possible)
Homogenization
Sampling (if needed, a press can be used)

Moreover, make sure to monitor humidity closely. Fluctuation of humidity above 10% can affect the accuracy of the analysis. After sampling, it is important to take 3–5 tests and average the test results to monitor homogeneity.

Which Vanta models are ideal for car catalyst analysis?

We offer several Vanta models for recycling automotive catalysts. The models differ in three main ways:

Analysis speed
Sensitivity
Ability to detect light elements, such as magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P), and sulfur (S)

For example, the Vanta L model is a cost-effective analyzer for catalyst classification. The analyzer has a PIN detector, so it can’t detect elements lighter than titanium. The mean analysis time of the Vanta L analyzer is about 40–60 seconds.

In contrast, Vanta C and M models use a silicon drift detector (SDD) to detect lighter elements. This is helpful for determining the content of silicon carbide (SiC) and controlling for sulfur (S) content. The mean testing time of these analyzers is about 15–20 seconds—3x more efficient than the analyzers equipped with PIN detectors.

The results and errors of palladium (in ppm) in the table below show these differences. The measurement results of the Vanta M analyzer in 5 seconds are similar to those of the Vanta L analyzer in 60 seconds.

Comparison of test results and errors of palladium (Pd) between Vanta L and M analyzers showing typical precision vs. measurement time

What features on the Vanta XRF analyzer make it suited for recycling automotive catalysts?

Repeatability of results: Built with Axon Technology™ electronics, every Vanta analyzer has a high degree of repeatability, so you get the same results from instrument to instrument and test to test.

Customizable: Catalyst substrates can vary in composition in different regions depending on local emissions regulations. You can easily adapt the analyzer to different catalyst substrates using customized User Factors to improve the test accuracy.

X-ray tube options: You can choose from silver, tungsten, or rhodium anode X-ray tubes. Note that the X-ray tubes for both tungsten and silver targets are ideal for analyzing automotive catalysts. The reason rhodium tubes are not preferred is that there are corresponding characteristic peaks on the spectrum when using X-ray tubes with a rhodium target.

Large measurement window: The large window on the Vanta analyzer enables the analysis of a large surface area, improving accuracy during testing of both uncrushed cores and ground samples.

Ruggedness: Recovering catalysts is a dusty process. The IP55/54 rating for dust and moisture protection helps keep the analyzer in good working condition. Vanta analyzers are durable and include a 3-year, comprehensive warranty to keep the cost of ownership low.

XRF accessories: In production processes, the Vanta Work Station turns the Vanta analyzer into a functional benchtop XRF for a comfortable, hands-free analysis. Benchtop use is ideal for final sample analyses prior to further refining at the recycling facility or at a smelter for PGM recovery.

Supports Industry 4.0 practices: The Vanta analyzer features network connectivity and is cloud-technology enabled. XRF data can be sent directly to an ERP system without user intervention.

Light element detection: With the rapid growth of automotive catalyst recycling, purification plants will tighten their requirements for incoming materials. The content of silicon carbide (SiC) and sulfur (S) is becoming more important when calculating the cost of incoming materials. As a result, XRF analyzers with silicon drift detectors (SDD) for light element detection will become a popular choice for car catalyst analysis.

ARE OLYMPIC GOLD MEDALS ACTUALLY MADE OF GOLD?

Mon, 17 Oct 2022 08:40:24 GMT

Olympic athletes strive to push their physical limits, break new records, and try the unimaginable. The most decorated Olympians have a collection of gold, silver, and bronze medals to celebrate their success.

But are Olympic medals actually made of gold, silver, or bronze as their names claim? Read on to find out!

The Composition of Olympic Gold Medals

You may be surprised to learn that Olympic gold medals are mostly made of silver with only a small percentage of gold.

The International Olympic Committee (IOC) has set rules for the production and design of Olympic medals. Their raw materials are specified as:

First place (gold medal): composed of mostly silver with a purity at least 92.5%, and plated with a least 6 grams of pure gold
Second place (silver medal): composed of silver with a purity at least 92.5%
Third place (bronze medal): composed of bronze, an alloy made of mostly copper and another metal (such as tin or zinc)

From these specifications, we can see that the Olympic gold medals are only plated with more than 6 grams of gold on the surface. The base material is still silver. On the other hand, the silver medals are made of silver, and the bronze medals are made of bronze (a mixture of copper and another metal).

Turning E-Waste into Treasure with “Green” Medals

The medals awarded at the Tokyo 2020 Summer Olympics were made of another surprising material—recycled e-waste! Considering there’s 80x as much gold in one ton of cellphones as there is in some gold mines, an impressive amount of gold can be found in old electronics at home.

For the Tokyo 2020 Summer Olympics, the Japanese Olympic Committee made a commitment to reduce the event’s carbon footprint. As part of this effort, they innovated the Olympic medal production by using recycled electronics to make "green” medals.

First, they called on the people of Japan to donate their used electronic products. Then they extracted the precious metals needed for the medals from this e-waste.

The initiative received widespread engagement. A total of 18,000 collection boxes were placed throughout the country, and 90% percent of Japan’s local authorities participated. In two years, the recycling initiative collected 78,985 tons of discarded gadgets. This haul included more than 6 million used mobile phones. Other donated devices were laptops, digital cameras, and handheld gaming devices.

Collection of cell phones for recycling

The devices yielded 32 kg (70.5 lb) of pure gold, 3,500 kg (7,716 lb) of pure silver, and 2,200 kg (4,850 lb) of pure copper. All 5,000 medals were made entirely from the recycled materials. This achievement marked a first for the Olympic Games and a significant step in the global movement to make sports more sustainable.

Elemental Analysis of Electronic Waste and Other Scrap

With Vanta XRF analyzers , users can sort recycled electronic waste and other scrap quickly and accurately. It can reliably identify most alloy and pure metals in 1–2 seconds. The analyzer can provide detailed information on the chemical composition of a material, enabling quick and precise identification of the grades of pure metals and alloys.

As a versatile tool for scrap recycling and precious metals testing, the Vanta analyzer can perform a variety of tests:

Sort out heavy alloys based on the low contents of silicon and aluminum elements
Analyze the electronic components of motherboards, identifying the electronic components containing precious metals (silver, gold, palladium, etc.), sorting and identifying toxic substances and lead-containing solders, and evaluating copper content in fine materials
Rapidly sort lead-containing glass and glass-ceramic products from recycling lines, detecting toxic elements
Analyze automotive catalyst scrap containing precious metals, such as palladium, platinum, and rhodium
Monitor the chemical composition of slags as it melts to control the quality and predict the life of a furnace

HOW MUCH IS A SCRAP CATALYTIC CONVERTER WORTH

Mon, 27 Sep 2021 11:19:36 GMT

What is a Catalytic converter?

A Catalytic converter is a device that helps your car produce cleaner emissions. It does so by using a catalyst, which is referred to as a catalytic converter . It consists of a substrate that accelerates a chemical reaction, to turn harmful gases from the exhaust system, into less polluting ones. This catalytic converter can also help the environment in another way, through catalytic converter recycling .

In addition to reducing waste, recycling catalytic converters is economically profitable because of the Platinum Group Metals (PGM’s) found in them. The catalyst component inside the catalytic converter is typically a combination of Platinum (Pt), Palladium (Pd) and Rhodium (Rh). These are all costly platinum group metals , or PGM’s.

With the proper sorting and processing of catalytic converter scrap , these metals can be recovered and reused to manufacture new catalytic converters and other equipment, in turn then sustaining the mining industry of these metals and pro longing the reserves in South Africa.

2 Steps to finding out how much is a scrap catalytic converter worth?

Knowing the value of catalytic converters , is merely impossible if you are a catalytic converter recycling company . When clients enter your workshop with a sealed or canned catalytic converters, the price of the scrap catalytic converter is easily determined, by taking the barcode from the housing of the catalytic converter and using the Ecotrade application. This application will automatically price the catalytic converter.

⮊ But it is not always that easy, as the Ecotrade application does not have all the barcodes in the system. How much is a scrap catalytic worth now?
In order to determine the price of a scrap catalytic converter , you will have to remove the precious metals dipped honeycomb from the ferrous housing. This honeycomb will have to be crushed to a fine powder. Once crushed to a powder you have to perform an XRF analysis. The handheld XRF analyser , will give you results of the precious metals, such as Platinum (Pt), Palladium (Pd) and Rhodium (Rh). With these results and the weight of your catalytic converter powder, you can use the Ecotrade application to calculate how much a scrap catalytic converter is worth .

Why measure catalytic converter powder with an XRF analyser?

For fast, accurate and representative results, sample preparation is required. Leading to a sustainable recycling business.
Trying to analyse the surface of a ceramic honeycomb can produce misleading results, leading to revenue loss.
The accurate identification of these metals, is vital since they are extremely valuable

An alternative way to find out how much the catalytic converter is worth

The Olympus VANTA handheld XRF analyser , can reflect the value of the catalytic converter powder on the screen by using the pseudo element’s function. This value can be per gram, per tonne or per kg.

The formula is quite simple:

The total value of the catalytic converter Powder, is the concentration shown on the analyser for Platinum, Palladium and Rhodium, multiplied by their respective daily stock rates, (either per gram or per kilogram). This value is then divided by 1000 in order to get the value per kg. This value is then multiplied by the weight of the catalytic converter powder , which will give you the true value of the catalytic sample.

In figures 1 and 2 below, it will all make sense.

The XRF analyser will perform this calculation:

Value per kg(V) = ((Pt% X Pt stock rate) + (Pd% X Pd stock rate) + (Rh% X Rh stock rate)) X 10

(V) = ((1140ppm X R598) + (980ppm X R1098) + (246ppm X R13750)) X 10

(V) = R 5139 per kg

This calculation you will have to perform yourself:

Sample Value (SV) = Value per kg X Weight of sample in Kg

(SV) = R5139 X 0.92kg

(SV) = R4727.88

The XRF analyser will perform this calculation:

Value per kg(V) = ((Pt% X Pt stock rate) + (Pd% X Pd stock rate) + (Rh% X Rh stock rate)) X 10

(V) = ((3300ppm X R598) + (330ppm X R1098) + (530ppm X R13750)) / 1000

(V) = R 9621 per kg

This calculation you will have to perform yourself:

Sample Value (SV) = Value per kg X Weight of sample in Kg

(SV) = R9621 X 0.92kg

(SV) = R8851.32
