Abstract
A procedure for sampling and analyzing the atmospheric presence of vinylidene chloride (75354) using solid sorbent collection and gas chromatographic analysis was developed. The vinylidene chloride was quantitatively trapped on charcoal, desorbed with carbon disulfide (75150), and analyzed by gas chromatography using a flame ionization detector. The upper limit for the method was dependent upon the concentration sampled and the relative humidity of the air being sampled. The lowest quantifiable limit was approximately 7 micrograms of vinylidene chloride per sample tube. At this loading, the desorption efficiency was greater than 80 percent and the relative standard deviation for the analysis of replicate samples was less than 10 percent. For general use, the recommended maximum sample volume is 7 liters collected at 0.2 liters per minute. Smaller sample volumes should be used near spills. Lower sampling rates should be used over a longer period of time.
