The UMEx 200 Passive Sampler collects sulfur dioxide (SO2) at 15.2 ml/min and nitrogen dioxide (NO2) at 17.3 ml/min. The UMEx 200 contains a tape treated with triethanolamine (TEA) and “blank" to sample from 15 minutes to 24 hours. Analysis is performed by ion chromatography (IC) with conductivity detection.
