The Source Branch of the Environmental Protection Agency's (EPA) Environmental Monitoring Systems Laboratory (EMSL) at Research Triangle Park, North Carolina has a program to develop stationary source test methods of known precision and accuracy for determining compliance with EPA standards. While participating in this program, Radian Corporation performed a field evaluation of a method for sampling and analyzing ethylene oxide (EO) in the vent stream from a dilute acid scrubber of a commercial sterilizer. The purposes of the test were to evaluate the ability of the analytical method to quantitate EO in scrubber emissions, to determine EO stability in sample containers, and to measure the EO concentration profile and EO-to-oxygen and EO-to-dichlorodifluoromethane (CFC-12) ratios during the initial sterilizer evacuation.
