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.

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 …

A while ago I attended the mining conference Exponor in Antofagasta, Chile and found it to be an immense, mostly open-air display and the technical program aimed at keeping the South American mines informed of the latest solutions for all aspects of their industry. In and amongst the huge mining machinery and vendors of everything – from dust masks to helicopters – was Malvern Panalytical. One trend did emerge from the people we did get to talk to at this event – a common theme of looking for ways to improve efficiency. This …

Whether it is for mineral exploration or mining waste analysis, there is a time lapse between bringing samples back to the laboratory, analysis and making decisions in the field.
Increasingly, governments are focusing on protecting the environment. Companies can be charged with hefty environmental fines. Minimise your company’s risk through quick analysis of undesirable environmental waste elements.
Imagine if you could have the flexibility to react quickly by analyzing samples while traveling between mine sites. Here’s a tip on how to set up a mobile lab in your car with the Epsilon …
