分散固相萃取-超高效液相色谱-串联高分辨质谱法测定新疆苹果中7种农药残留
Determination of 7 Pesticide Residues in Xinjiang Grown Apple by Dispersive Solid-Phase Extraction Combined with Ultra Performance Liquid Chromatography-High Resolution Tandem Mass Spectrometry
摘要
Abstract
To quickly obtain information about trace pesticides in Xinjiang grown apple, we investigated 7 commonly used pesticides during apple planting, and established a dispersive solid phase extraction combined with ultra performance liquid chromatography-high resolution tandem mass spectrometry (UPLC-HRMS/MS) method to quickly screen and quantitatively analyze the target pesticides. The results showed that good linearity was observed for all 7 analytes with correlation coefficients above 0.99. The limits of detection (LODs) were in the range of 0.003-0.1 mg/kg and the limits of quantification (LOQs) ranged between 0.02 and 0.5 mg/kg. Average recoveries were in the range of 95%-119% with relative standard deviation (RSD) less than 10% (n = 3). The method allowed for the rapid multi-residue analysis of pesticides in Xinjiang grown apples to be exported without any false-positive results.关键词
