This method is used for the determination of phenyl ether diphenyl mixtures. The sample is collected on silica sorbent tubes, extracted with benzene, and analyzed by GC/FID. The working range is 0.1 to 10 ppm (0.7 to 70 mg/m³) for a 10 L air sample. Better sensitivity may be achieved with a capillary column in place of a packed column. A DB-17 column with appropriate instrumental conditions is recommended. NOTE: This is Method S73 in fourth edition format.
