Head-space methods are described for the determination of residual acrylonitrile in acrylonitrile-butadiene-styrene resins and in olive oil, which simulates fatty foodstuffs. Dimethylformamide was used as solvent for the resin, with flame ionization detection. The injection of water into the resin dispersion prior to head-space analysis greatly enhances the detection capabilities. The use of a nitrogen-selective detector required dimethyl sulphoxide as the solvent. The determination of acrylonitrile in olive oil was carried out employing both types of detector. The detection sensitivity was much greater with the nitrogen-selective detector.
介绍了顶空法用于测定丙烯腈-丁二烯-苯乙烯树脂和模拟脂肪类食品的橄榄油中的残留丙烯腈。以二甲基甲酰胺作为树脂的溶剂，采用火焰离子化检测。在顶空分析之前向树脂分散体中注入水可大大提高检测能力。使用氮选择性检测器时需要二甲基亚砜作为溶剂。采用两种检测器对橄榄油中的丙烯腈进行了测定。氮选择性检测器的检测灵敏度要高得多。
