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 ...
