GAS SAMPLING SYSTEM
September 1st 2004

A new gas analysis sampling system from Perma Pure reduces the water content of gases from humid environments to optimal humidity for electrochemical sensors (ECS).

The Micro-Gass system does this without altering the concentrations of analyte gases such as hydrogen sulphide, chlorine or methane in the samples.

Chiller/condensers remove water by condensation so water soluble gases are lost when they dissolve in the condensate. The Micro- GASS system removes water directly from the vapour phase instead, using Nafion membrane gas dryers. The membrane selectively removes water vapour without removing water-soluble analytes.

Drying is a continuous, selfregenerating process. No routine maintenance is needed.
