X-Ray Fluorescence Testing (XRF Assay) it is a useful tool for measuring the concentration of impurities in the precious metals. It merely uses X-Rays to determine purity. After bathing the metal with X-Rays, the spectrometer analyses the unique fluorescent rays emitted by the metal and then compare them with the specific atomic structure.
