Classification: G01N

Abstract:
A data processor for fluorescent x-ray spectroscopy, said data processor comprising:first calculating means for calculating first theoretical x-ray intensity which is theoretically expected to be obtained from a first measurement in fluorescent x-ray spectroscopy of a standard sample with known composition inside a chamber by taking into account x-ray attenuation according to environmental condition inside said chamber when said first measurement was taken;sensitivity-calculating means for calculating element sensitivities for elements in said standard sample from said first theoretical x-ray intensity calculated by said first calculating means and measured intensity obtained by actually measuring said standard sample by fluorescent x-ray spectroscopy;memory means for storing said calculated element sensitivities;second calculating means for calculating second theoretical x-ray intensity which is theoretically expected to be obtained from a second measurement in fluorescent x-ray spectroscopy of an unknown sample by taking into account x-ray attenuation according to environmental condition inside said chamber when said second measurement was taken; andanalyzing means for calculating content of each component contained in said unknown sample from said second theoretical x-ray intensity, measured intensity obtained by actually measuring said unknown sample by fluorescent x-ray spectroscopy and said element sensitivities stored in said memory means.
