Hydrogen Removal Mechanism

Ag 400 Zeolite operates through a combination of physical adsorption and chemical adsorption of hydrogen.

Simultaneously with physical adsorption, a chemical reaction with hydrogen takes place. Ag 400 contains active silver ions; during the hydrogen removal process, hydrogen bonds with these silver ions to form stable linkages, which are then embedded within the crystal lattice of the molecular sieve carrier. This process ultimately achieves the objective of hydrogen removal. The maximum exothermic temperature generated during this reaction is approximately 277°C; consequently, no hydrogen explosion hazards arise, ensuring a high level of safety. Furthermore, the process does not generate water, thereby effectively preserving the vacuum integrity.

Usage Instructions:

Ag 400 Silver Molecular Sieve is a highly efficient material for hydrogen removal.

Ag 400 is supplied in the form of spherical granules and requires no prior activation before use. This hydrogen scavenger should be placed at the ambient-temperature end (typically the lower section) of the high-vacuum equipment. (Note: If the equipment requires maintenance involving the replacement of Ag 400, it is recommended to first reactivate the existing Ag 400—by heating it to 260°C for a minimum of four hours—before adding a fresh batch of Ag 400.)
