Problems solved by technology

However, after a long time in this adsorption process, the adsorption material decreases or no longer has the function of adsorption, and the impurities accumulated inside will not only reduce the life of the trap, but also affect the test results
The overall replacement will increase the cost a lot

Abstract

The invention discloses a hydrogen trapping trap, which comprises a shell, a first purifier and a second purifier, the first purifier and the second purifier are arranged in the shell, a gas inlet anda gas outlet are formed in the two ends of the shell respectively, the gas inlet is communicated with the gas inlet end of the first purifier, the gas outlet end of the first purifier is communicatedwith the gas inlet end of the second purifier, the gas outlet end of the second purifier is communicated with the gas outlet, the first purifier is filled with a first absorbent, the second purifieris filled with a second absorbent, a first heating device for heating the first purifier and a second heating device for heating the second purifier are arranged in the shell, the first absorbent is gamma aluminum oxide, and the second absorbent is an MOF material.

Description

technical field [0001] The invention relates to a trap for hydrogen gas. Background technique [0002] The trap is a gas purification device with an adsorbent inside, which is often used for the purification of carrier gas, gas and assisted gas in gas chromatography. The trap is installed after the gas inlet valve, which can effectively adsorb the impurity components in the gas, ensure the purity of the gas and improve the efficiency of the gas, save resources and improve the sensitivity of the instrument. When it is installed in the split / splitless inlet and septum purge inlet, it can effectively adsorb the organic samples in the carrier gas and prevent the samples from condensing in the subsequent pipelines to cause pipeline blockage. The basic structure of traps currently on the market is to fill a stainless steel tube with certain adsorption materials. When in use, the carrier gas or other gases are passed through the stainless steel tube, and the internal filler filter...
