X-ray fluorescence spectrometer

It is used for analysis of harmful elements in RoHS directive, analysis of alloy (copper alloy, stainless steel, etc.) and geological mineral composition; and thickness measurement of metal coating. The working principle is based on the fact that when X-rays interact with matter, the elements in the sample absorb X-rays and then re-radiate them. This re-radiated X-ray spectrum can be measured and analyzed.
