This method is designed for the determination of 1,3-cyclopentadiene. The sample is collected with maleic anhydride coated Chromosorb 104 sorbent tubes, desorbed with ethyl acetate, and analyzed by GC/FID. The working range is 25 to 150 ppm (67 to 400 mg/m³) for a 3 L air sample, based on sampler capacity at high relative humidity. NOTE: This method revises P&CAM 294.
