UMEx 100 Passive Samplers, for Formaldehyde, Pk/10 Overview

UMEx 100 Passive Sampler, for formaldehyde, glutaraldehyde, and acetaldehyde; detection range from 5 ppb to 5 ppm; 15-minute to 24-hour samples and 7-day samples (sampling periods between 24 hours and 7 days have not been evaluated); single use only, pk/10
Limited shelf-life; freezer storage required
Meets OSHA Method 1007 specifications
If sampling in an atmosphere containing formalin, see www.skcinc.com/instructions/1795.pdf for field study information.

The convenient UMEx 100 Passive Sampler features sensitive method-validated chemistry for detection of low levels of formaldehyde. The single-use UMEx 100 contains a tape treated with 2,4-dinitrophenylhydrazine (DNPH) for reliable collection. Sampling rates are validated from 15 minutes to 24 hours or 7 days. Analysis is performed by high-performance liquid chromatography (HPLC).

UMEx 100 Passive Sampler for Formaldehyde — The Professional's No. 1 Choice
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 aluminized 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" 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 occupational sampling or in an appropriate location for environmental monitoring.

Using the UMEx 100 Passive Sampler
Sampling with the UMEx 100 Passive Sampler for formaldehyde 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" position. Clip the sampler on a worker for occupational sampling up to 12 hours or in an appropriate location for environmental monitoring for up to 24 hours or for 7 days. When sampling is complete, simply 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 high-performance liquid chromatography. The UMEx 100 sampler is designed for single use only. Do not reuse UMEx samplers.

UMEx 200 for Sulfur Dioxide and/or Nitrogen Dioxide
UMEx 200 uses tape treated with triethanolamine (TEA) for the passive collection and analysis of sulfur dioxide and/or nitrogen dioxide. Analysis is by ion chromatography (IC) with conductivity detection. See UMEx 200 for Sulfur Dioxide and/or Nitrogen Dioxide for more information.
