This method is for the determination of epichlorohydrin. The sample is collected on a charcoal tube, desorbed with carbon disulfide, and analyzed using GC/FID (flame ionization detector). The working range of the method is 0.5 to 16 ppm (2 to 6 mg/ m³) for a 20 L air sample.
NOTE: This is Method S118 in a revised format.
