XRF (X-ray fluorescence) is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the Fluorescent X-Ray Spectrographic Analysis book of a sample by measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary X-ray source.

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. However, an XRF cannot generally make analyses at the small spot sizes. W.J.

X-Ray?uorescence analysis (XRF) has developed into a well-established multi-elemental analysis technique with a very wide?eld of practical app- cations, especially those requiring nondestructive analytical methods.

Over a long period of time, steady progress of XRF was made, both methodological and instrumental. Within the last decade, however, advancements in te- nology, Reviews: 1. X-ray fluorescence is now a well established method of analysis both in the laboratory and industry.

The fact that the method is essentially nondestructive makes it particularly attractive for the Author: E. HALL. The papers presented in this volume of Advances in X-Ray Analysis were chosen from those presented at the Fourteenth Annual Conference on the Applications of X-Ray Analysis.

This conference, sponsored by the Metallurgy Division of the Denver Research Institute, University of Denver, was held on. The specific X-ray tube geometry and variable excitation source configuration allows for analysis of a large range of the periodic table.

Due to the low beam energies however, these measurements are not as precise as those that can be produced using a laboratory XRF, though we demonstrate that this does not affect the utility of the instrument Cited by: Discovery.

QUALITATIVE ANALYSIS THEORY. When a sample is irradiated with high energy x-ray photons it will emit characteristic x-ray lines whose energy depends on the atomic number of the element of the sample material. If a sample consists of a chemical compound or mixture, its fluorescence spectrum will also be complex.

X-ray tubes accelerate high-energy electrons at a target within the tube that is then caused to fluoresce X-rays.
