Description

The UME^x 300 Passive Sampler accurately and reliably samples workplace exposure to Ammonia. Constructed of tough polypropylene, the UME^x 300 contains a sulphuric acid treated tape for reliable collection of ammonia. Samplers are provided in individual aluminiumised pouches that can be reused to transport the sampler to a laboratory after sampling. For convenience and quality control assurance against contamination, each sampler incorporates a “blank correction” section in addition to the active sampling section so there is no need to send extra samplers to the laboratory. Analysis is by ion chromatography (IC) with conductivity detection for the ammonium ion.

The shelf-life date is printed on a label on the outside of each pouch for easy inventory management. The UME^x 300 Sampler includes a clip for attachment to a worker’s collar for personal sampling, or in an appropriate location for area sampling.

Ammonia is one of the most commonly produced industrial chemicals. Workers can be exposed in ammonia in the following industries:

Agricultural (fertilizers)
Janitorial services (cleaners)
Food and beverage (refrigeration and fermentation)
Remediation (removal of contaminates)
Fuel
Manufacturing of plastics, explosives, pesticides, textiles and dyes
