GM-Series GASS Module

Modular Gas Analysis Sampling System designed for Systems Integrators

The GASS-Module is a cost-effective approach to gas sample conditioning that removes water, particulates and coalescable liquids from gas samples while retaining analyte gases.

GASS Modules bring maximum performance at minimal cost to systems integrators and OEM manufacturers of gas analysis systems by deferring all control to the central system, eliminating any electronics in the module and reducing the size and complexity of the device.

Unlike chiller/condensers that remove water by condensation, GASS Modules very selectively remove water directly from the vapor phase using patented Nafion® membrane dryers.  Consequently, water-soluble analyte gases are not lost through dissolution in the condensate, and the water content of the sample is reduced to a much lower dew point.  Drying is a continuous, self-regenerating process.  No routine maintenance is required.

GASS Modules also eliminate acid mist problems with an integral coalescing filter with automatic drain to remove sulfuric acid.  GASS Modules can be integrated inside environmental enclosures or indoors along with analyzers, since they consume little space.

GASS Modules accept samples containing as much as 75% water at rates up to 12 liters per minute and temperatures as high as 150°C.  Particulates down to 1µm are removed, sulfuric acid mists are eliminated, and water content is reduced to a dew point as low as -35°C, while oxides of carbon, nitrogen, and sulfur are quantitatively retained within the sample.
