Abstract
A sorption pump for high vacuum applications that is suited for use in gas analyzers such as mass spectrometers. The pump includes a housing containing a quantity of getter material and a diffusion barrier in the gas inlet to the housing. A finite period of time is required for gas molecules in the vacuum analyzer system to cross the barrier, thus providing a window during which gas pulses can be accurately analyzed.
