蔬菜和食用菌中多种氨基甲酸酯农药残留的UPLC-MS/MS的确证方法

Determination of 19 Carbamates Pesticide Residues in Vegetableand Edible Mushrooms by UPLC-MS/MS

摘要: 建立了蔬菜和食用菌中19种氨基甲酸酯农药残留的液相色谱串联质谱（UPLC-MS/MS）确证方法.实验方法采用丙酮和乙腈混合溶液提取，凝胶渗透色谱净化，经浓缩后由HPLC-MS/MS测定.实验结果表明：方法定性定量准确，灵敏度高，满足了国内外限量要求，具有较好的推广价值.回收率为70.1%～95.7%，RSD为1.63% ～13.83%，方法最低检出限0.01 mg/kg.

Abstract: A UPLC-MS/MS method to determine 19 carbamate insecticides in vegetable and mushroom was developed. The samples were extracted with a mixedsolvent of acetonitrile and acetone, purified by passing through a gel permeation chromatographic column and then concentrated and determined by UPLC-MS/MS. The results indicated that the method has a high qualitative and quantitative accuracy, and high sensitivity. It also meets the domestic and overseas limitation demand and worths popularizing. The corresponding recoveries were 70.1% ～95.7%, RSDs are 1.63% ～13.83% with a method determination limit (MDL) of 0.01 mg/kg.
