Total Reflection X-ray Fluorescence Analysis. Section 1
Total Reflection X-ray Fluorescence Analysis Section 1: Introduction 4 1.1.1- Total reflection phenomenon Contrary to the behavior of the visible light photons, for X-rays any medium is less dense than vacuum and any solid is optically less dense than air. This results in a refracted beam deflected toward the interface. Following this

X-Ray Fluorescence (XRF) - SERC
An X-ray fluorescence (XRF) spectrometer is an x-ray instrument used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that are similar to an electron microprobe ( EPMA ). However, an XRF cannot generally make analyses at the small spot ...
