PRODUCT DESCRIPTION

The Perma Pure GASS-2040 is able to condition the most challenging gas samples directly on the stack. The Perma Pure GASS-2040 conditions high-flow, high-moisture samples and eliminates acid mists or ammonia if present. It processes the toughest samples, with flows of up to 25 lpm and moisture contents in excess of 50%. The GASS-2040 can be mounted anywhere, including on the stack flange with an integral stack probe, which eliminates heated sample lines.

This instrument contains three temperature-controlled zones mounted in an environmentally sealed, NEMA-4X housing. In the first zone, the sample passes through a heat exchanger, then through a coalescing particulate filter to remove particles down to 0.1 micron. Acid mist, if present, are coalesced then removed by an automatic drain. If ammonia is present, a proprietary ammonia scrubber removes it. In the second zone, the sample passes through a proprietary Nafion dryer and the initial portion of the dryer is heated about the sample dew point to prevent condensation and to created water vapor removal. In the third zone, the sample passes through the remainder of the dryer, further reducing the dewpoint down as low as -25⁰C, depending upon dryer model selected and sample flow rate.

Conditioning the sample immediately after it leaves the stack improves its analytical integrity, eliminates the need for expensive heated sample lines and reduces calibration time which saves calibration gases.
