Use the X diffraction qualitative analysis manner and the qualitative analysis device

摘要

PURPOSE:To automatically conduct a qualitative analysis sing an X-ray diffraction while maintaining an analyzed result with high reliability. CONSTITUTION:An X-ray analysis profile is obtained for an unknown sample (102). The kind of an element included in the sample is obtained by the element analytic measurement, and all internal substances to be considered from the X-ray diffraction profile are selected by referring to standard peak card data (104). The combination of all the selected substances is taken, and a plurality of sets of the substance combinations are predicted (106). The substance combination which does not include all the elements obtained as above of the predicted combinations of all the substances is deleted from the data, the standard peak card data corresponding to the combination of the residual substances without deletion is compared with the profile in terms of the degree of conformance, and suitable internal substance combination is selected.
