Assay Technology 575 Nitrous Oxide Monitor badge clipped to collar.

Assay Technology’s 575 Nitrous Oxide Monitor is a convenient and cost-effective way to measure nitrous oxide (N2O or “laughing gas”) exposure in the workplace. Our 575 badge contains activated molecular sieves, which trap the nitrous oxide during sampling. Because nitrous oxide is naturally found in the atmosphere, we strongly recommend the use of a field blank during each sampling event.

Description

At the lab, the samples are desorbed by transferring the sieves into a vial, adding water, and capping the vial.  The water will displace the nitrous oxide, which gathers in the headspace of the vial.  Finally, the headspace is analyzed by GC/ECD for the nitrous oxide.
