Nafion™ tubing, a highly selective tubing that helps increase accuracy during gas analysis, while reducing risk of damage to your device from condensation. The Nafion™ polymer is unique in its ability to seamlessly transfer moisture from one side of a membrane to the other side as a first order kinetic reaction.

Nafion™ Technology

The Nafion™ polymer transfers water molecules from one side of the membrane to the other by a first order kinetic reaction. This is unlike a porous membrane that depends on the physical size of molecules. Nafion™ Polymer selectivity is based on chemical reactivity, not the size of the molecule – therefore, not traditional permeation. The Nafion™ polymer selectively transfers water vapors, leaving most analytes in the gas stream untouched.

The driving force for the Nafion™ polymer to transfer water molecules is the difference in humidity levels on either side of its membrane. The Nafion™ polymer aims to attain equilibrium of the partial pressure of water vapor on the inside and the outside of its membrane.
