PERMA PURE LLC Mini-GASS™ User’s Manual Doc. #212: Revision: 00A Page 6 of 32 General description Proven tube-in-shell membrane technology is the basis of the Mini-GASS™ Conditioning System, which selectively removes water vapor from a gas stream. The driving force is the vapor pressure differential between the sample gas and a purge gas counter-flowing outside the tubing. This difference quickly dries the gas stream.
