1. Introduction
Perma Pure GASS Module™ sample conditioning systems are designed to prepare gas samples for
analysis. The GASS Module system will remove, particulates, mists and water vapor without removing
compounds being monitored.
A heated sample line is connected to the top fitting on the GASS Module (see Figure 1). Sample gas flows
to the filter where particulates are removed and/or mists are coalesced. After filtration, sample is passed
through the Nafion® Dryer where water vapor is selectively removed. Sample is now ready for analysis.
Standard Features Include:
• Filter - Particulate and/or Coalescing
• Perma Pure Nafion ® Gas Dryer
