Perma Pure 1

Overview

Perma Pure manufactures high performance gas sample conditioning systems using the unique substance Nafion™. Nafion™ is a flourocarbon copolymer of Teflon® and sulfonic acid.  The Teflon® makes the Nafion™ resistant to almost every chemical and the sulfonic acid has a very high water-of-hydration. While the Nafion™ is able to selectively transfer water vapor across its membrane, making it able to remove up to 90% of water vapor from a wet gas stream or add water vapor into dry gas stream. While transferring water vapor, it also maintains analytes in the gas sample or stream. This means that gas dryers made with Nafion™ remove the water vapor from a sample very quickly, but many chemicals and compounds are retained in the sample.

Cross Company is able to offer Perma Pure coolers, driers, CEM accessories, and sample conditioning products to our customers within our territory.

Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
