A generalized approach to quantitative energy-dispersive X-ray fluorescence analysis using fundamental parameters.

摘要

A general procedure for energy-dispersive X-ray fluorescence is presented. Based on fundamental parameters and optional use of scatter peaks, it is applicable to a large variety of samples using different excitation sources. Complete algorithms are used for both absorption and enhancement corrections for the most general cases in the quantitative EDXRF analysis. Quantitative analysis for unknown samples is based on an element- and sample-independent constant, which can be calculated from any standard or known mass and composition. The procedure has been implemented as part of a larger software package AXIL-QXAS, which includes spectrum-acquisition and spectrum-analysis and runs on a personal computer.
