| titleOfInvention | Crystal quantification method |
| abstract | A calibration method is prepared by preparing a standard mixed powder obtained by pulverizing and mixing crystals, and a highly accurate quantitative method is provided. SOLUTION: (a) a step of obtaining crushed crystals of two or more kinds of crystals having different crystal forms or crystallinity with an airflow pulverizer, and (b) weighing the crushed crystals by a predetermined amount, respectively, Putting into a hollow container provided with a mixed medium of an elastic body, and vibrating or rotating the hollow container to obtain a plurality of standard mixed powders having different crystal content or crystallinity; and (c) the standard mixed powder. X-ray powder diffraction measurement, and preparing a calibration curve correlating with the weight of each crystal in the standard mixed powder or the crystallinity of the standard mixed powder, and (d) crushing the crystal mixture to be quantified And (e) powder X-ray diffraction measurement of the pulverized crystal mixture, and the content of each crystal in the crystal mixture or crystallization of the crystal mixture from the calibration curve prepared in step (c). Step to calculate degree Determination method of the crystal, which comprises. [Selection] Figure 1 |
