High temperature and high pressure gas adsorption instrument

rIntroduction to the fully automatic high temperature and high pressure gas adsorption instrument
During the process of gas storage and separation of adsorbent materials, it is usually necessary to know the amount of gas adsorption, and the storage and separation processes are often carried out under ultra-high pressure conditions. of. When testing the amount of adsorption, static volumetric equipment must be used to detect how much gas is adsorbed by the adsorbent material as the pressure changes within a fixed volume. Sometimes it is necessary to observe the changes in the amount of gas adsorbed by the adsorption material at different temperatures. This is the role of our high temperature and high pressure adsorption instrument. For some samples, the amount of adsorbed gas at different temperatures is completely different. At this time, we will also test the changes in the amount of gas adsorbed by the sample at different temperatures. For all these complex operations, JinAipu Technology's fully automatic high-temperature and high-pressure gas adsorption instrument has completely realized automation!
JinAipu Technology is a professional manufacturer of high-temperature and high-pressure adsorption instruments. Its fully automatic high-temperature and high-pressure gas adsorption instruments currently reach a maximum temperature of
degrees Celsius and a maximum pressure of
br/>Br. Under such high temperature and high pressure conditions, the overall quality requirements for the instrument are very high. The sealing method must be
sealing technology to ensure no air leakage. To ensure that the test pressure piping system connection must be an integral container design and use micro-welding technology, otherwise air leakage will easily occur between components and must be
The connected pneumatic valve instead of the solenoid valve must use an original vacuum pump to ensure the high vacuum required for the test. Of course, it must also be a high-quality pressure sensor to monitor the real-time changes in pressure.

Sample Usage
The instrument uses a miniature matrix cavity reference cavity, combined with a high-sealing pipeline system, a high-precision pressure measurement system and a high-precision gas adsorption capacity calculation model, eliminating the need to use a large sample amount for dispersion. The test error of a small sample amount of milligrams to a few grams can achieve the same test accuracy as the traditional instrument using a sample amount of tens of grams. The small sample amount can effectively improve the test efficiency.
