摘要

Provided is a crystal-phase quantitative analysis device capable of more easily performing quantitative analysis of a sample including a plurality of crystal phases. The crystal-phase quantitative analysis device is provided with: a means for acquiring powder diffraction patterns in a sample; a means for acquiring information about a plurality of crystal phases; a means for acquiring respective fitting functions for the plurality of crystal phases; a means for performing all-pattern fitting on the powder diffraction patterns by using the fitting functions and acquiring the result of the all-pattern fitting; and a means for calculating the weight ratio of the plurality of crystal phases on the basis of the result. Each of the fitting functions is selected from a group consisting of first fitting functions using integration intensities obtained by all-pattern decomposition, second fitting functions using integration intensities obtained by observation or calculation, and third fitting functions using profile intensities obtained by observation or calculation.
