Operating principle of YA-c argon purification unit:

YA-c type Shengyu argon purification consumables use high-temperature metal alloy getter, and its surface will react with some impurities such as oxygen and CH4. Moreover, at high temperature (300-700 ℃), these impurities will diffuse from the surface to the inside of the material to maintain the reaction ability of the surface and new impurities, which is a puzzle to be solved by the process. The service life of equipment consumables has been extended to achieve the purpose of energy saving, income increase and consumption reduction.

The non-evaporable zirconium aluminum 16 getter is used as the purifying agent. At a certain temperature, the getter can form stable compounds or solid solutions with the trace impurities O2, N2, H2, H2O, CO, CO2, CH4, etc. in argon, so as to achieve the purpose of refining argon. Argon purifier can be used with American Thermoelectric, German Spike and OBFL; The direct-reading spectrometer, fluorescence spectrometer and glow spectrometer produced by many spectrometer companies, such as ARL in Switzerland, Shimadzu in Japan, Nach in Italy, Arang in the UK, and Ruili in Beijing, are used together to ensure the reliability and stability of the analytical data with ultra-pure gas quality.

High-temperature getters are some metal alloys. Its surface will react with some impurities such as oxygen and CH4. Moreover, at high temperature (300-700 ℃), these impurities will diffuse from the surface to the inside of the material to maintain the reaction ability of the surface and new impurities.
