A multiresidue method for determining 12 carbamate pesticides in purple cabbage, orange, watermelon, cucumber, cowpea and Lactuca sativa L. employing multi-plug filtration cleanup (m-PFC) and ultra-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) was developed. M-PFC was carried out by cleanup at dispersive solid phase extraction (d-SPE), one m-PFC tip-filtration, two m-PFC tip-filtration and other methods (1-3 m-PFC cleanups). Results demonstrated that filtration simplified the cleanup method compared with d-SPE and other m-PFC methods (1-3 m-PFC cleanups). The method validation results showed that the method was linear, selective and accurate. The limits of quantification (LOQs) were 0.05-5.0 μg/kg, and the recoveries were in the range of 70.1-119.9% in different matrices. Although matrix effects were observed, they were successfully compensated using matrix-matched calibration. Finally, the developed method was successfully applied to detect pesticides in real samples.

快速多插头过滤净化和超高效液相色谱/串联质谱检测法测定典型蔬菜和水果中的12种氨基甲酸酯类杀虫剂。

采用多塞滤净化（m-PFC）和超高效液相色谱-电喷雾电离串联质谱（UPLC）的多残留方法测定紫甘蓝，橘子，西瓜，黄瓜，cow豆和紫花莴苣中的12种氨基甲酸酯农药-ESI-MS / MS）。通过在分散固相萃取（d-SPE）上进行净化，一次m-PFC尖端过滤，两次m-PFC尖端过滤以及其他方法（1-3 m-PFC净化）来进行M-PFC。结果表明，与d-SPE和其他m-PFC方法（1-3 m-PFC净化）相比，过滤简化了净化方法。方法验证结果表明，该方法线性，选择性好，准确。定量限（LOQ）为0.05-5.0μg/ kg，不同基质的回收率在70.1-119.9％范围内。尽管观察到基质效应，但已使用基质匹配校准成功补偿了它们。最终，该方法成功地用于实际样品中农药的检测。
