Headspace electron-capture-gas chromatographic methods are described for the quantification of vinylidene chloride monomer in poly(vinylidene chloride) containing films and in film-packaged foodstuffs. Quantification of vinylidene chloride was possible at levels down to 0.001 mg/m2 in the films and 0.005 ppm in the foodstuffs. The results of a small survey of the amounts of this compound in packaging films and foodstuffs purchased from retail outlets are reported.
描述了顶空气相电子捕获色谱法，用于定量测定含聚偏二氯乙烯的薄膜以及薄膜包装食品中的偏二氯乙烯单体。薄膜中偏二氯乙烯的定量下限可达0.001毫克/平方米，食品中为0.005 ppm。报告了一项对从零售店购买的包装薄膜和食品中该化合物含量的小型调查结果。
