1. Introduction
The Perma Pure Micro-GASS is designed to reduce the humidity of gas samples to 20% to 80% RH, the
optimal humidity for Electrochemical Sensors. The Micro-GASS system will remove particulate matter and
water vapor from a gas stream without removing the compounds being monitored. The system consists of
a heated particulate filter, a partially heated Perma Pure Nafion gas dryer, a sample pump, and controls for
temperature and sample flow, assembled in a 12" x 12" x 7" NEMA3R enclosure.
2. Micro-GASS Components
2.1 Heated Filter
The first step in conditioning the sample is filtering out particulate. The filter is a disposable
1micron “encapsulated micro-fiber” filter element housed in a Kynar filter body for corrosion
resistance. Surrounding the filter body is a heated aluminum shell. The filter is
thermostatically controlled at 95°C to prevent aerosols from forming in the sample stream.
