Nafion™ Membranes for Analytics and Instrumentation

Nafion™ Membranes Support New Gas Analysis Techniques

Nafion™ membranes are exceptionally efficient at humidifying and drying gas streams, a critical step in making gas samples ready for chemical analysis. Samples are prepped for analysis by having a gas flow on one side of a Nafion™ membrane with an appropriate dry or wet gas flowing on the other.

Nafion™ membranes can operate in environments with harsh chemicals and high temperatures, while retaining properties over many use cycles. Because of this, they are used in many types of analysis equipment, including:

  • Medical devices used for breath gas analysis applications and humidification of oxygen and air for ventilator applications
  • Gas sample dryers used in a wide range of gas analyzers and scientific analysis equipment
  • Gas humidifiers for fuel cells, incubators, and environmentally controlled test chambers
  • Gas sample conditioning systems that measure nitrogen oxides (NOx) and sulfur oxides (SOx) emissions for chemical environmental management systems (CEMS) and process monitoring
