Grab sampling of tracer gas/air mixture is a convenient method for conducting a survey of air infiltration rates in homes. Gas samples may be collected with a hypodermic needle and stored in Vacutainers. This technique is particularly suited when sulphur hexafluoride (SF[6]) is used as a tracer gas, as only a small quantity of gas sample is required to measure its concentration with an ion capture detector/chromatograph. Because an extended delay is probable between collection and analysis of gas samples, storage stability tests of SF[6]/air mixture in 20 mL Vacutainers were conducted. Samples can be stored for at least 21 days without significant changes in their concentrations. The gas sampling and analysis procedures are described in det...
