GASS Gas Analysis Sampling Systems
The line of GASS gas analysis sampling systems prepare samples for analysis by removing water, acid mists and ash without altering the concentrations of analytes. New to this line is the GASS-2040 system, with a NEMA 4x stainless steel enclosure, dual-temperature controllers to eliminate acid mist, dual dryers to accommodate high sample flows and integral stack mounting capabilities. The unit eliminates heated sample lines by connecting directly to the probe and drying the sample completely before transporting it to the ground.

MDH series dryers
The compact, heated MDH series dryers combine Nafion technology with a heating element to dry hot, wet, sample gases prior to analysis, increasing sample accuracy and reducing damage to downstream analysis equipment. The dryers were specifically created to dry gas samples with dew points higher than the ambient temperature, without requiring additional heating or insulation. Proprietary Nafion technology selectively removes only water from samples gases, leaving the rest of the gas sample unaffected. Unlike chillers and condensers, the MDH dryers remove water directly from the vapor phase, preventing the loss of water-soluble gases through dissolution in condensate. Designed to handle gas flows of up to 1 L/m, the dryers can dry gases with as much as 30% water by volume.
