PERMA PURE
DM™-Series gas dryers combine selectivity
of Nafion
®
gas dryers with the simplicity of
desiccant canister dryers. Gaseous sample
flowing through the dryer contacts only Nafion
tubing, which selectively absorbs water vapor
while retaining the remaining sample compo-
nents in the gas stream. Water passing
through the tubing wall is absorbed by the
molecular seive desiccant. Scattered blue
indicating crystals can be observed through
the clear window to monitor the condition of
the desiccant.
