ABSTRACT:
A method and apparatus for enriching a gas of lower molecular weight with substances of higher molecular weight contained therein, comprises using first and second molecular pumps connected together, with the second pump having a conveying direction different from the first pump, and wherein a feed line for the gas terminates in a working chamber of the first molecular pump and its exhaust side includes extraction means for the enriching component. The gas is conducted to the working chamber of the first molecular pump and a portion of the gas is conveyed at the intake side of the molecular pump by means of the second pump. The substances of higher molecular weight are collected and extracted at the exhaust side of the first molecular pump.
