2. Sorption pump or adsorption pump
Normative definition: "A fixation pump in which the gas is mainly fixed by the physisorption of a substance with a large real surface area (e.g. a porous surface)."
2.1 Principle
Some porous materials such as activated carbon, zeolites and silica gel have very large specific surface areas (surface area developed per unit mass of the solid substance) ranging from several hundred square metres per gram to over a thousand
Pumping action is achieved by the phenomenon of low-temperature adsorption of a given gas onto a given product. The lower the temperature, the greater the...
