This method is for the determination of vinylidene chloride.The sample is collected on charcoal sorbent tubes, is desorbed in toluene and allowed to stand for 8 hours prior to analysis by GC/FID. The working range is 0.5 to 5 ppm (2 to 20 mg/m³) for a 5 L air sample. Note: This method revises P&CAM 266.
