UMEx 500-200 with Callouts

The single-use SKC UMEx 200 Passive Sampler effectively collects sulfur dioxide (SO2) at a sampling rate of 15.2 ml/min and/or nitrogen dioxide (NO2) at 17.3 ml/min. The sample medium (tape treated with triethanolamine [TEA]) and a "blank" section of tape are contained in one sampler saving time and money. The lightweight UMEx 200 clips in the breathing zone for easy occupational sampling. Samplers are provided in individual aluminized pouches that can be used to transport the sampler to a laboratory. The label on the outside of each pouch contains the shelf-life date for easy inventory management.

Using the UMEx 200 Passive Sampler
Sampling with the UMEx 200 Passive Sampler for sulfur dioxide and/or nitrogen dioxide is easy and requires no pump or training. Simply remove the sampler from the pouch, record sampling information, and slide the cover to the "on" or sampling position. Clip the sampler on a worker for occupational sampling up to eight hours. When sampling is complete, slide the cover to the "off" position, place the sampler back in the pouch immediately, and seal. Send the sampler to an accredited laboratory for analysis by solvent extraction ion chromatography (IC) with conductivity detection.

Potential Sources of Workplace Exposure to Sulfur Dioxide and Nitrogen Dioxide

Sulfur dioxide is used in industry as a(n):
  • Intermediate in sulfuric acid manufacture
  • Bleaching agent
  • Disinfectant
  • Fumigant
  • Solvent
  • Refrigerant
  • Food preservative
  • Reagent in the manufacture of magnesium, sodium sulfite, and other chemicals
Other sources are:
  • Copper smelting
