This method is for the determination of hexachloro-1,3-cyclopentadiene. The sample is collected on two sorbent Porapak T tubes, desorbed in 1 mL of hexane followed by a 1 hour ultrasonic bath, and analyzed by GC with a 63Ni electron capture detector system. The working range is 0.005 to 0.2 ppm (5 to 2400 mg/m³) for a 5-L air sample. NOTE: This method revises P&CAM 308 which was evaluated with a reference method which involved sampling with impingers of hexane and analysis by GC/ECD.
