This method is for the determination of hexachlorobutadiene. The sample is collected on XAD-2 sorbent tubes, desorbed in 2mL hexane with an ultrasonic bath, and analyzed by GC/ECD. The working range is 0.01 to 2.0 mg/m³ for a 100-L sample. An alternate column, DB-210, may be used with appropriate changes in instrumental conditions. Note: This revises method P&CAM 307.
