A gas chromatographic method is described for acrylonitrile monometer (AN), using a nitrogen/phosphorus detector. Procedure for the analysis of AN in 5 food simulants (water, 3% acetic acid, heptane, 50% ethanol, and 8% ethanol) as well as in the polymer matrix are included. The quantitation limit for direct injection of AN/food simulant solution is 0.04 ng AN/microliter. AN-based polymers are dissolved in N,N-dimethylacetamide and injected directly. Residual AN in the polymer can be quantitated at the 0.5 ng/microliter level. Results of migration studies are also presented.
描述了一种使用氮磷检测器的气相色谱法测定丙烯腈单体（AN）。其中包括了在5种食品模拟物（水、3%乙酸、庚烷、50%乙醇和8%乙醇）以及聚合物基质中分析AN的程序。直接进样AN/食品模拟物溶液的定量限为0.04 ng AN/微升。基于AN的聚合物溶解于N，N-二甲基乙酰胺中并直接进样。聚合物中的残留AN可在0.5 ng/微升水平进行定量。还给出了迁移研究的结果。
