The new GASS-II Gas Analysis Sampling System from Perma Pure prepares gas samples for analysis. Developed to remove acid mists that can damage analyzers, it also removes other coalescable liquids, water and particulates without altering the concentrations of typical analyte gases such as CO, CO2, HCl, NOX, O2 and SO2. The product includes a separately heated coalescing filter with automatic drain to remove acid mists before drying.
