るが、このような試料のX線回折を求めることは
従来不可能であつた。 There is a strong desire to obtain X-ray diffraction of a sample at a relatively low temperature, and several proposals have been made. The cooling gas spraying method is a method in which a cooling gas made by vaporizing liquid nitrogen is sprayed onto a solid or liquid sample to lower the temperature of the sample. Although this spray cryogenic apparatus is capable of lowering a solid or liquid sample to a low temperature, there is a problem in that the entire apparatus including auxiliary equipment is extremely large-scale, making it difficult to use easily. Devices have also been implemented in which a sample is sealed in a vacuum-filled container for insulation and then cooled. Such an apparatus has no problem when the sample is solid, but when the sample is liquid, the sample dissipates into the vacuum container, so it is not suitable for measuring liquid samples. Although it is known that certain components in gas oil crystallize at low temperatures, it has previously been impossible to obtain X-ray diffraction of such samples.
