Description
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. This badge is NON-RETURNABLE
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.
- PLEASE NOTE: Starting with lot 3C20, the black return container is no longer necessary. (Lot “3C20” means the lot was made March 2020.)
- With this lot, the holding time changed from 7 to 14 days.
This badge collects the following:
- Nitrous oxide
Special Notes
Important Handling Instructions:
- Remove the badges from pouches immediately before sampling. Even though the badge is shut, it could still be collecting nitrous oxide.
- Before and after use, store the badges in a room that has no nitrous oxide.
- After sampling, place each badge into a return envelope provided. Do not put more than one badge into each envelope.
- PLEASE NOTE: Starting with lot 3C20, the black return container is no longer necessary. (Lot “3C20” means the lot was made March 2020.)
Before sampling, ship and store at room temperature. After sampling, store and ship at room temperature.Return the samples to the laboratory within 14 days of sample collection. Sample while gas is in use. Functional range of the badge: 1 hour – 8 hours. Minimum recommended sampling time is 1 hour.
