The dilemma  

Gaseous sample analysis requires a clean, dry sample to produce accurate and reliable results. Filters will remove entrained particulates, but removing moisture from a sample without affecting the analyte is not so simple. Refrigeration dryers will remove water by condensation and collection,but water soluble analyte gases will dissolve in the condensate and be removed as well. Dessicant dryers will absorb water, but also typically absorb analyte gases. Permeation dryers will preferentially remove water, but also remove analytes.

Solution            

Nafion gas dryers are a superior alternative. They continuously and highly selectively remove water from gaseous samples without affecting analytes, reaching final sample dew points as low as -45°c.

Operations      

Permapure is the sole manufacturer of the tubing made of Nafion under exclusive license of Dupont, manufacturer of Nafion. This tubing is highly corrosion resistant and selectively permeable to water making it ideally suited for drying or humidification of gas samples as water vapour can be added to or removed from the sample without changing the composition of the sample.

Industrial Uses:

• Includes gas sample conditioning. Premapure offers complete systems to accomplish this sample preparation. Fuel cell humidification is a rapidly developing industrial application as well.
  

Medical Uses:

• Drying of breath for anesthesia monitoring
• Respirator monitoring
• Metabolic testing
• Humidification of respirator air or supplemental oxygen

Scientific Uses:

• Exploitation of the electrochemical and ion exchange properties of Nafion
• Sample conditioning for laboratory analyses

Premapure is operating predominantly in the following market sectors :

• Incineration
• Iron And Steel Industry
• Water Treatment Plants
• Environment Control
• Chemical Industry
• Cement Plants
• Automotive Industry
