On the other hand, in the case where no protective film is provided, the diffraction lines become broader due to moisture absorption, and the diffraction lines disappear when the diffraction angle is 0 large. Conditions are room temperature 23℃, relative humidity 70

This is because 2 deliquesced and became a solution within the 40 minutes required for measurement. Xi for MgC-C2 with retention is
When measuring the change in the diffraction line over time, there was no change in the X-string diffraction line even after 48 hours. In addition to hydrocarbon oil, liquid paraffin or solid paraffin can also be used for the protective film. The solid paraffin is heated and melted and then dropped onto the four parts of the glass substrate 2. The stability when using liquid paraffin and solid paraffin was 96 hours and 2nd, respectively.

Characteristic line 6 is the case where a protective film is provided, and the peak indicated by arrow P is a diffraction line due to the polyethylene (5) protective film. Characteristic line 5 is the case without a protective film. The peak of polyethylene can be subtracted by data processing, and since it does not overlap with the diffraction line of MgC-C2, it is possible to accurately measure the diffraction line of MgC-02.

を進めることが可能となる。According to this invention, in a sample preparation method for analyzing a material that changes depending on moisture in the atmosphere, a water-repellent protective film is provided on the surface of the material, so moisture in the atmosphere is separated from the analysis material, making it stable. X-ray diffraction, fluorescence-xxi analysis, and infrared spectroscopy can be performed. Furthermore, since this analytical sample preparation method uses a protective film obtained by a simple method such as dripping or hot melting at the edge of the blade, no skill is required for its preparation (6). Furthermore, when using the preparation method of the present invention, a large-scale air conditioning device is no longer used as a core wall, and it can be applied to the existing θ analyzer to proceed with physical property analysis of hydrophobic materials from various angles.
