Abstract:
An X-ray fluorescence spectrometer for measuring intensities of secondary X-rays emitted from a sample, which includes a single layered thin film or a multi-layered thin film formed independently or on a substrate, by irradiating the sample with primary X-rays, said apparatus comprising:a measuring line evaluating means for calculating, for each specified secondary X-ray line to be measured, a first theoretical intensity at a specified thickness and a composition of each of layers of the thin film and a second theoretical intensity at the thickness and the composition thereof when the thickness or the concentration has been changed by a predetermined quantity, for calculating a precision of a thickness or a precision of the concentration based on the first and second theoretical intensities, and for determining applicability or inapplicability of an analysis using the specified secondary X-ray line to be measured based on the calculated thickness precision or the calculated concentration precision; and a display control means for causing a display unit to display the applicability or inapplicability of the analysis determined by the measuring line evaluating means.
