UMEx 100 Passive Sampler for Formaldehyde
The UMEx 100 Passive Sampler for formaldehyde was developed in collaboration with the National Institute of Working Life in Umea, Sweden.
Constructed of tough polypropylene, the single-use UMEx 100 contains a tape treated with 2,4-dinitrophenylhydrazine (DNPH) for reliable collection of formaldehyde. Samplers are provided in individual aluminiumised pouches that can be used 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.
The shelf-life date is printed on a label on the outside of each pouch for easy inventory management. The UMEx 100 Sampler includes a clip for attachment to a worker’s collar for personal sampling or in an appropriate location for area sampling.
