Description
Our 555 Ethylene Oxide Monitor is the most convenient way to measure personal exposure to ethylene oxide gas. Employees who work with EtO should be regularly monitored to maintain a safe working environment. This easy-to-use badge can collect 15-minute STEL samples as well as full-shift, 8-hour TWA/PEL samples. This badge is NON-RETURNABLE
Ethylene oxide is collected on a flexible, inert charcoal wafer treated with hydrogen bromide. The hydrogen bromide converts ethylene oxide to 2-bromoethanol. At the lab, the excess hydrogen bromide is neutralized with sodium carbonate. Then, the 2-bromoethanol is extracted with 90/10 toluene/acetonitrile and analyzed by GC/ECD. No further derivatization is required.
This badge collects the following:
- Ethylene oxide
