UME^x 200 Passive Samplers

The lightweight UME^x 200 clips in the breathing zone for easy personal sampling. The sample medium (tape treated with triethanolamine [TEA]) and a "blank/correction" section of tape are contained in one sampler saving time and money. Samplers are provided in individual aluminiumised 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.

Same chemistry as active OSHA Method ID-182
Ready to use
Accurate, reliable personal sampling
Lightweight sampler clips easily in the breathing zone
Economical , low cost, single use sampler
Safe — no glass or chemical liquids in the sampler
No pump or training required
Sample medium and blank/correction in one unit
Accurately measures personal workplace exposure to sulphur dioxide and/or nitrogen dioxide from 15 minutes to 8 hours (Not suitable for new STEL of 0.25 ppm)
3-week sample storage at ambient temperature

SKC Research has validated the UME^x 200 Passive Sampler for 24 hour ambient air sampling of sulphur dioxide and nitrogen dioxide to complement federal EPA reference methods. The validated concentration range for sulphur dioxide is 0.4 to 8 ppm (15 minutes to 24 hours); nitrogen dioxide is 0.05 to 8 ppm (15 minutes to 24 hours).

Applications for Sulphur dioxide

Intermediate in the manufacture of sulphuric acid
Bleaching agent
Disinfectant
Fumigant
Solvent
Refrigerant
Food preservative
Reagent in the manufacture of magnesium, sodium sulphite and other chemicals

Applications for Nitrogen dioxide

Agricultural silos
Arc or gas welding, especially in confined space
Electroplating plants
Food and textile bleaching
Jewelery manufacturing
Nitric acid production
Nitrogen fertiliser production
Nitro-explosive production
Pickling plants
