摘要：

A sampling and analytical method for the determination of vinylidene chloride in air is presented. Vinylidene chloride can be quantitatively trapped on charcoal over a wide range of concentrations. The collected vapors are desorbed with carbon disulfide and analyzed by gas chromatography utilizing a flame ionization detector. The analytical column is packed with Durapak OPN. The lower limit for the method is approximately 7 μg of vinylidene chloride per sampling tube. The breakthrough volume was found to be dependent upon the concentration sampled and the relative humidity of the air sampled. The overall precision of the analytical method is 5% (relative standard deviation). Copyright 1979, American Industrial Hygiene Association
