This method is for the determination of dichloroethyl ether. The sample is collected on charcoal sorbent tubes, desorbed in carbon disulfide, and analyzed by GC/FID. The working range is 1.7 to 46 ppm (10 to 270 mg/m³) for a 15 L air sample. This method may be used for simultaneous analysis of two or more analytes by changing the chromatographic conditions (e.g. temperature programming) . High humidity during sampling will greatly reduce breakthrough volume. Note: This is Method S357 in a revised format.
