This method is for the determination of dibutyl phosphate. The sample is collected on PTFE filters, desorbed with acetonitrile, and analyzed by GC with a phosphorous flame photometric detection system. The working range is 0.2 to 1.2 ppm (2 to 10 mg/m³) for a 200-L air sample. Note: This method revises P&CAM 297.
