Abstract: A simultaneous multi-compnoent at residue level analytical method by Capillary Column Gas Chromatography FPD (P mode) for 12 o.p. pesticides is established. The average detection limit is 0.2 ng and the recovery is between 99.94%±3.23%. The injection coefficient of variation is 3.18%. The method is highly sensitive, accurate, precision, and suitable for the detection of most of o.p. pesticides.

摘要： 应用毛细管色谱(Capillary Gas Chromatography. CGC)对我国稻区取代六六六的12种残留水平的有机磷农药进行一次性快速分离定性,峰高外标法定量,平均检测极限为0.2ng,回收率为99.94%±3.23%,变异系数为3.18%。本法灵敏度较高,准确、重演性好,适用于多种有机磷农药的检测。
