چکیده

A gas-chromatographic analysis of vinylidene chloride (1,1-dichloroethylene) is presented. Vinylidene chloride was sampled by adsorbing on activated carbon. It was desorbed with carbon disulfide. The desorption efficiency was 97.2 +/- 1.05 (mean +/- standard error). The analytical column was packed with 10% Apiezon L on acid-washed Chromosorb-P. The analysis was conducted on a gas chromatograph equipped with a flame ionization detector.
