  • Title: Gas-liquid chromatographic determination of vinyl chloride in alcoholic beverages, vegetable oils, and vinegars.
    Author: Williams DT, Miles WF.
    Journal: J Assoc Off Anal Chem; 1975 Mar; 58(2):272-7. PubMed ID: 1141164.
    Abstract:
    Vinyl chloride in foods is determined by gas-liquid chromatography either by direct injection of vinegars and alcoholic beverages or by headspace analysis of vegetable oils. The lower limit of detection is 10-15 ng/ml for direct injection and 1-10 ppb for headspace analysis. Confirmation by gas chromatography-mass spectrometry, single ion monitoring at m/c 62, is possible at 50 ppb for either method. The levels of vinyl chloride bottles were 0.0-1.6 mu-g/ml for alcoholic beverages, 0.0-8.4 mu-g/ml for vinegars, and 0.3-3.3 ppm for peanut oil.
