Title Development and validation of a protocol for field validation of passive dosimeters for ethylene oxide excursion limit monitoring
Bibliographic information Apr.1991, Vol.52, No.4, p.145-150. Illus. 10 ref.
Abstract The protocol uses a field exposure chamber with concurrent sampling using Tedlar air-sampling bags. The bags are analysed after sampling by gas chromatography with flame ionisation detection (GC-FID). The chamber design allows all dosimeters to be exposed at the same time in the field. The sampling and analysis procedure determines the actual concentration of ethylene oxide (EtO) present during the dosimeter's exposure, and estimates if EtO concentrations vary from point to point in the dosimeter array during the exposure. In chamber operation, the accuracy of the standard generator used to calibrate the GC-FID was independently verified in the field by the standard additions method. The study reports the sampling biases and estimates the stability of collected EtO samples in Tedlar bags.
