UME^x 400 Passive Sampler for Aliphatic Amines

The SKC UME^x 400 Passive Sampler collects amines in the 0.5 to 10 ppm range. The UME^x 400 Passive Sampler contains a tape treated with 1-Naphthyl-isothiocyanate (NITC). Each sampler incorporates a “blank/ correction” section in addition to the active sampling section. Analysis is by high-performance liquid chromatography with UV detection (HPLC-UV) for identification of amines that may be present in the sample.

Sampling with the UME^x 400 Sampler is very easy and requires no pump or training. Simply remove the badge from the pouch, record sampling information on the back of the sampler, and slide the cover to the “on” position. Clip the sampler on a worker for personal sampling or in an appropriate location for area sampling for up to 8 hours. When sampling is complete, simply slide the cover to the “off” position, place the sampler back in the pouch, and seal. Send the sampler to an accredited laboratory for analysis by high-performance liquid chromatography with UV detection (HPLC-UV). The UME^x 400 sampler is designed for single use only. Do not reuse UME^x samplers.
