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 …

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 …
