GC-MS-MS was used to analyze for multiple pesticide residues in fresh fruits and vegetables. Nineteen pesticides, including fungicides, herbicides, organophosphorus insecticides and chlorinated insecticides were spiked into seven different fruit and vegetable matrices and analyzed. The specificity of GC-MS-MS provided for low detection limits (ranging from 1-5 ppb) and unambiguous spectral confirmation for the target compounds in these complex matrices. Good precision was obtained (RSD values ranged from 1 to 9%), even at the 10 ppb level, without extensive sample clean-up steps.
气相色谱-串联质谱法用于分析新鲜水果和蔬菜中的多种农药残留。将包括杀菌剂、除草剂、有机磷杀虫剂和氯代杀虫剂在内的19种农药添加到7种不同的水果和蔬菜基质中进行分析。气相色谱-串联质谱法的特异性实现了低检测限（范围为1 - 5 ppb），并能对这些复杂基质中的目标化合物进行明确的光谱确认。即使在10 ppb的水平下，无需大量的样品净化步骤，也能获得良好的精密度（相对标准偏差值范围为1%至9%）。
