The ethylene oxide monitor is an easy method to sample for either 15 minute STEL or full shift 8 hour exposures.  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 50/50 acetonitrile/toluene and analyzed by GC/ECD.  No further derivatization is required.
