Low-level transuranic (TRU) waste to be stored underground at the Waste Isolation Pilot Plant (WIPP) has the potential to generate low levels of reactive gases such as HCl, NO{sub x} H{sub 2}S, and NH{sub 3} through radiological, biological, and chemical (corrosion) processes. Because of the low levels of gas expected to be produced (< 1 ppM), a method was developed which includes the simultaneous sampling of gases using chemically treated filter papers and analysis of the extracted ions by ion chromatography. To determine the effects of humidification on the collection and determination of reactive gases, a humidification system was added to the trace gas generator system to produce a relative humidity approximately equal to that in the Humid Test Bin. This humidification system consisted of gas washing bottles filled with saturated brine (NaCl) that has been shown to produce a relative humidity of approximately 75% in the temperature range of 68{degree}F to 86{degree}.
