DM Series Desiccant Membrane Dryer (Desiccant/Membrane) gas dryers combine the selectivity of Nafion® gas dryers with the simplicity of desiccant canister dryers. Gaseous sample flowing through the dryer contacts only Nafion tubing, which very selectively absorbs water vapor from the gas while quantitatively retaining the remaining sample components in the gas stream. Typically water passes through the Nafion tubing wall and is carried away by a dry purge gas; instead, in DM Series dryers, desiccant packed around the tubing provides a dry purge environment. No power or other utilities are required.
