Zero gas refers to the gas used to adjust the minimum scale of a gas analyzer, and the gas that displays zero when it enters the analyzer; zero gas should be free of the analyte or interfering substances, containing only components unrelated to the measurement. The zero gas generator produces pure zero gas through multi-stage physicochemical processes, including gas compression and pretreatment, catalytic oxidation, and adsorption filtration.

Support columns are installed at the four corners of the lower end face of the generator body. An air inlet pipe is installed in the middle of the lower end face of the generator body.

[0006] Preferably, the ends of the gas filling pipe, the gas outlet pipe, and the gas inlet pipe all extend to the inside of the pretreatment chamber. A molecular sieve purifying agent is provided on the inside of the pretreatment chamber. The molecular sieve purifying agent is an aluminosilicate material.

[0013] 1. This utility model, by setting up an outlet pipe, a gas supply pipe, and a heating layer, can raise the temperature of the pretreatment chamber. At the same time, inert gases such as nitrogen can be introduced into the pretreatment chamber through the gas supply pipe. When heating the molecular sieve, the heat provided can provide sufficient energy for the adsorbed impurity molecules to overcome the adsorption force on the surface of the molecular sieve micropores, thereby desorbing them from the micropores and restoring the micropores of the molecular sieve to an adsorbable state, thus achieving reuse.

The user can lift the baffle upward with the handle, causing the housing and filtering mechanism to move away from the inside of the circular groove. The housing can then be rotated to remove it from the baffle. Afterward, the strip plate, bottom plate, and activated carbon adsorption plate can be removed from the housing. The activated carbon adsorption plates are connected... The bottom plate and the lowest activated carbon adsorption plate are connected by a connecting rod, allowing the activated carbon adsorption plate to be separated for easy maintenance or replacement. Simultaneously, when the housing leaves the inner side of the circular groove, the vertical pipe and top rod leave the inner side of the first connecting pipe. The sealing plate, no longer under downward pressure, is pushed upward by the second spring, causing it to engage with the inner side of the fixing ring and seal it, preventing gas leakage from the first connecting pipe. Gas can then enter the housing through another first connecting pipe to continue filtration. This invention facilitates maintenance of the filtration mechanism without requiring downtime, ensuring high working efficiency. Attached Figure Description

The bottom plate 1802 is connected to the lowest activated carbon adsorption plate 1801 via connecting rods 1803, allowing the activated carbon adsorption plates 1801 to be separated for easy maintenance or replacement. Simultaneously, when housing 14 leaves the inner side of circular groove 12, vertical pipe 15 and top rod 17 also leave... Inside the first connecting pipe 13, the sealing plate 1602, no longer under downward pressure, is pushed upward by the second spring 1605. The sealing plate 1602 is engaged inside the fixing ring 1601, sealing the fixing ring 1601 and preventing gas from leaking from the first connecting pipe 13. The gas can then enter the housing 14 through another first connecting pipe 13 to continue filtration. This invention can heat the molecular sieve, reuse it, and facilitate the maintenance of the filtration mechanism 18 without stopping the machine, thus ensuring working efficiency.
