The SKC UMEx 300 Passive Sampler accurately and reliably samples workplace exposure to ammonia. With its 39.92 ml/min sampling rate, the sensitive UMEx 300 detects ammonia to 2.4 ppm for a 15-minute sample, 0.075 ppm for an eight-hour sample, and 0.025 ppm for a 24-hour sample. Each sampler contains a length of sulfuric acid-treated tape and a blank section of tape built into the sampler. Analysis is by ion chromatography (IC) with conductivity detection for the ammonium ion or visible absorption spectrometry.
