This method is used for the determination of chloroprene.The sample is collected on a charcoal sorbent tube, desorbed in carbon disulfide, and analyzed using GC/FID. The method is sensitive enough to determine concentrations as low as 12 ppm in 15 minute samples taken at 0.2 L/min. Note: This method is S112 with an improved GC column in a new format.
