| 摘 要： | 建立了对农药杀虫剂中添加隐性成分氯虫苯甲酰胺进行液相色谱初筛,再用液相色谱–串联质谱仪进行定性,最后用液相色谱进行定量的方法。样品加入四氢呋喃和乙腈溶解,用DAD检测器和C18柱,以乙腈–缓冲溶液(V/V,45/55)为流动相,对氯虫苯甲酰胺初筛和定量,用液相色谱–串联质谱电喷雾正离子扫描定性。实验证明,该方法操作简单,准确度、精密度均良好。

| Abstract: | An analytical method to determine chlorantraniliprole in pesticide by high performance liquid chromatography （HPLC） and high performance liquid chromatography-tandem mass spetrometry （LC-MS/MS） was developed. Samples were dissolved by adding tetrahydrofuran and acetonitrile, chlorantraniliprole was initially sieved and quantitatively determined by HPLC with a DAD detector and C18 column, used acetonitrile-buffer solution （V/V, 45/55） as mobile phase. And LC-MS/MS with electrosprayin positive ion scan mode was used to qualitatively analysis. The experiments showed that the method was simple, fast and accurate. |
