【摘要】 目的:建立对中药、保健品、食品中有机氯类、拟除虫菊酯类等多种农药残留的气相色谱-电子捕获检测器(GC-ECD)测定方法。方法:选用DM-1毛细管柱,通过柱程序升温,对17种农药进行同时检测。结果:各种农药分别在10~200 ng/ml、20~400 ng/ml浓度范围内与峰面积呈良好的线性关系,检出限范围为0.092~3.25 pg。结论:本方法快速、简便、准确、具有良好的通用性。 更多还原

【Abstract】 Objective:The residues of 17 sorts of organochlorine and pyethroid pesticide in crude drug and traditional medicine preparations and foods were determined.Methods:The pesticides in samples were extracted on different qualitite standard.The pesticides were seprated by DM-1 column with the column temperature program.Results:The effect of septaration by DM-1 column was good.The pesticides of 17 sorts could be separated perfectly.There was good linear relation over the range of 10~200 ng/ml,20~400 n... 更多还原
