X-ray fluorescence analyzer

摘要

An x-ray fluorescence analyzer and method. The analyzer and method use a single radio-active source, such as, <241>Am to determine the composition of a metal alloy or precious metal. The method compensates for Rayleigh scattering by first determining a scaling factor using a particular energy line in the spectrum of the test material and comparing that line to the same energy line for a pure metal. Based on the scaling factor the energy spectrum for the pure is compensated and then subtracted from the energy spectrum of the test material at discrete points.
