This method is for the analysis of vinyl bromide by GC/FID in ambient air. The working range is 0.3 to 33 ppm (1.3-145 mg/m³) for a 6 L air sample. The sample is collected on charcoal sorbent tubes and analyzed by GC/FID after desoprtion in ethanol, followed by ultrasonic agitation. Note: This is Method P&CAM 349 in a revised format.
