摘要
建立了气相色谱法测定食品添加剂不溶性聚乙烯聚吡咯烷酮(PVPP)中的N,N’-二乙烯基-咪唑啉酮的检测方法,样品采用丙酮提取,气相色谱仪-氮磷检测器检测,内标法定量,浓度在0.1~3.2μg/m L范围内具有良好的线性,线性相关系数为0.9999,方法的定量限为1mg/kg,加标回收率为102.0%~106.1%,变异系数2.44%~5.26%,同时本方法也为气相色谱法的建立与开发,提供了帮助。
Reverse gas chromatography method was developed for the determination of Free N, N＇ divinylimidazolidone in Insoluble Polyvinylpolypyrrolidone （PVPP） in food additives. The samples were extracted by acetone, Quantitative determined by internal standard method and detected by GC-NPD. The results showed that the linear range of Free N, N＇ -divinylimidazolidone was 0.1 - 3.2μg/mL, Correlative coefficient was 0.9999. The limit of quantitation was 1 mg/kg, the average recoveries were 98.0% - 103.1%, the coefficients of variation were 2.63% - 5.26%. In addition, the method provided information in establishing a new detecting method by gas chromatography.
