PROBLEM TO BE SOLVED: To provide a preparation method of a measurement sample capable of obtaining a sufficient X-ray diffraction profile.SOLUTION: The preparation method of a measurement sample for use in a powder X-ray diffraction method includes a process of mixing a first material to be measured and a second material having an X-ray extinction distance longer than that of the first material. As the mixing ratio between the first material and second material in this process, a mixing ratio is used such that the X-ray diffraction intensity of the mixed measurement sample is higher than that of the first material and the X-ray extinction distance of the measurement sample is longer than the radius of a capillary filled with the measurement sample. |
