X-Ray Fluorescence (XRF)

XRF is a robust technique, combining high precision and accuracy with straightforward, fast sample preparation. It can be readily automated for use in high-throughput industrial environments, plus XRF provides both qualitative and quantitative types of information on a sample. Easy combination of this ‘what?’ and ‘how much?’ information also makes rapid screening (semi-quantitative) analysis possible.

The technology used for the separation (dispersion), identification and intensity measurement of a sample’s X-ray fluorescence spectrum gives rise to two main types of spectrometer: wavelength dispersive (WDXRF) and energy dispersive (EDXRF) systems.

The weighing step is of major importance in sample preparation by fusion since it has a direct impact on the analytical results.
Let’s see five best practices to ensure repeatability and productivity while weighing.
REPEATABILITY
Find the right weighing method
There are three weighing methods in sample preparation: sample-to-flux ratio, catch weight and manual weighing. The far best choice is sample-to-flux ratio since it ensures great repeatability and can be performed automatically using LeDoser-12 instrument. With this method, no software correction is required.
Avoid transferring the weighed content into a different container
You should always weigh …

Safe, high-quality food is something that many of us take for granted. Occasionally though, a scandal occurs that shocks the world. Whether it is plastic in chocolate, melamine in milk powder, lead in noodles or lead in water, the consequences can be devastating for the people and businesses involved.
Consequences can be health-related for consumers but also affect the profitability and reputation of the brands of the companies involved. Governments around the world have responded to these liabilities with increased oversight and regulations – for example, the Food Safety Modernization Act …

Lower commodity prices, weaker demand, environmental regulations, lower ore grades, and higher running costs are some of the main challenges that the mining industry has to deal with every day. But now is a good time, while activities are off-peak, to adopt sustainable cost control measures beyond the traditional and generate data that will improve productivity and process stability. Reducing C1 cash costs and increasing revenues can be accomplished with the extensive use of automation and robots in the field and in the laboratory, to gain in productivity and remain …

Outdoor air pollution can have many sources, both anthropogenic (power generation, vehicle emissions, industrial and agricultural emissions, etc.) and natural, for instance, volcanic eruption, wind erosion or wildfires.  A key area of concern is the Suspended Particulate Matter (SPM), which can have adverse effects on health, particularly in the particle size ranges under ten microns.  These are further characterized by two designations – PM10 (2.5 – 10 micron) and PM2.5 (<2.5 micron), with PM10 having the ability to penetrate deep into lungs, and PM2.5 able to permeate throughout the body …

Claisse® LeNeo was launched in 2014. It’s a one-position instrument that is used in various types of industries.
Read the following lines to discover why it’s the right instrument to use in universities and colleges’ labs.
Reason 1 – Safety
The safety of students should always be an academic institution’s main concern. Manual fusion is often used in colleges and universities’ laboratories, but it involves the manipulation of hot vessels and is not representative of technologies used in the labor market. By being fully automatic, LeNeo instrument guarantees cold-to-cold operation and avoids the …

Gelatin is a well-known ingredient in the food, pharmaceutical, and cosmetic industries. It is colorless and flavorless and is used for example as a thickener in many sweets or in capsules. Gelatin is a natural product and can be derived from collagen obtained from e.g. cattle, fish, chicken, and horses. Depending on source and preparation methods (acidic or alkali) many different types of gelatin with varying quality are obtained.
The need for analysis
You might remember a few years ago there was news from China about toxic gelatin capsules containing high concentrations …

After the introduction of the Zetium at Pittcon in March 2015, I look back at the most exciting product launch I have ever been part of with great awe of what we have achieved. I still remember my euphoric mood on my flight back from New Orleans. Not because of amenities on board or the limited leg room, no, it was about what had happened in the past months in the running up to the launch of our latest product, the Zetium XRF spectrometer.
Now you must know. I have been …

When performed correctly, fusion is the sample preparation technique that leads to the obtention of the most precise and accurate XRF and ICP analytical results. Among all factors that need to be considered to get great glass disks or solutions and therefore excellent analysis, the choice of flux is one of the most important.
Let’s discover why.
An Indispensable Chemical
The flux forms the matrix of the disk analyzed by the spectrometer. It must melt before the sample dissolves into it. An adequate flux allows to:

Optimize the solubility of the sample and …

For quality and process control many elemental analysis techniques are available. Let’s see how ICP, AAS, ICP-MS, ICP-OES and X-ray fluorescence spectroscopy (XRF) stack up are traditional techniques used in many industries. Each of these techniques has a number of advantages and disadvantages giving the analyst the flexibility to choose which technology suits best. When the required limits of quantification are above 1 ppm (µg/g), or when the non-destructive analysis is required, XRF is a very attractive technique that should be considered, especially when analyzing solids, powders, slurries, filters, and …

What is fusion?
You might already know that the choice of the sample preparation method for X-Ray Fluorescence (XRF) or Inductively Coupled Plasma (ICP) atomic emission spectroscopy analysis is critical to obtain precise and accurate results with the spectrometer.
Have you ever heard about fusion? Let’s demystify this technique and have a look at its benefits when compared to pressed pellets.
What is it exactly?
Fusion for XRF analysis consists of mixing a ground sample with a borate flux (lithium or sodium) inside a 95% platinum / 5% gold crucible, heating around 1000 °C with …
