XRay Fluorescence (XRF) SERC
An Xray fluorescence (XRF) spectrometer is an xray instrument used for routine, relatively nondestructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelengthdispersive spectroscopic principles that are similar to an electron microprobe (EPMA). However, an XRF cannot generally make analyses at the small spot sizes typical of EPMA work (25 microns), so it is ...
