Abstract

The invention discloses a sample stage for measuring a liquid sample by an X-ray diffractometer, wherein the sample stage includes a crucible furnace with adjustable temperature, a quartz crucible forholding a sample and a temperature control thermocouple; the upper surface of the crucible furnace is sunken inwards to form a groove, the quartz crucible is placed in the groove, and the temperaturecontrol thermocouple is inserted in the crucible furnace for adjusting the temperature of the crucible furnace. According to the sample stage for measuring the liquid sample by the X-ray diffractometer, the temperature control thermocouple inserted in the crucible furnace is used for controlling the temperature of the crucible furnace, so the quartz crucible placed in the crucible furnace is heated and has the temperature controlled, the problem that a water bath pot is needed to be externally connected for heating when a liquid is tested by a diffractometer at present is solved, and at the same time, the heating range is broadened.

Description

Technical field [0001] The invention relates to the technical field of detection equipment, more specifically, it relates to a sample stage for measuring liquid samples for an X-ray diffractometer. Background technique [0002] Liquid has the structural characteristics of short-range order and long-range disorder. There are two types of research methods. One is direct measurement of structure, that is, the measurement is carried out with instruments; the other is computer simulation method to obtain solution structure. It is worth noting that molecular simulation alone cannot obtain real solution structure data, which lacks verification; experimental data is still the benchmark and the basis for obtaining ideal data. [0003] But so far there is no proprietary instrument for the determination of solution structure. In current measurement methods, the method that can directly and accurately obtain solution structure information is an experimental method based on scattering. The in...
