建立了液相色谱-串联质谱（LC-MS/MS）同时测定农产品中多种农药残留的方法。样品用乙腈提取。通过GPC/石墨化碳柱SPE和硅胶/PSA筒柱SPE除去共萃取物。使用预定的MRM通过LC-MS/MS测定测试溶液中的农药。菠菜、糙米、大豆、橙子和番茄中124种农药的回收率为0.1 μg/g，其中121种农药的回收率为70 ~ 120%（RSD≤15%）。应用该方法对239种农产品进行了农药残留量调查，在98种农产品中检出49种农药残留。
A method for the simultaneous determination of multiple pesticide residues in agricultural products was developed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The sample was extracted with acetonitrile. Co-extractives were removed by GPC/graphitized carbon column SPE, and silica gel/PSA cartridge column SPE. Pesticides in the test solution were determined by LC-MS/MS using scheduled MRM. Recoveries of 124 pesticides from spinach, brown rice, soybean, orange and tomato were tested at the level of 0.1 µg/g, and those of 121 pesticides ranged from 70 to 120% (RSD≤15%). Pesticide residues in 239 agricultural products were investigated by this method, and residues of 49 pesticides were detected in 98 agricultural products.
