摘要:

采用改进的QuEChERS方法,结合超高效液相色谱-串联质谱法(UPLC-MS/MS),建立了热带水果中杀虫双残留的测定方法。热带水果经含1%(v/v)乙酸的乙腈溶液二次提取,200 mg N-丙基乙二胺(PSA)、100 mg C18、300 mg MgSO4和500 mg柠檬酸氢二钠净化。采用CAPCELL CORE PC亲水色谱柱进行分离,在负离子多反应监测(MRM)模式下检测,外标法定量。结果表明,杀虫双在0.1~10.0 μg/L范围内线性关系良好,相关系数(r2)为0.9993,检出限和定量限分别为0.015 μg/kg和0.05 μg/kg,加标回收率为81.0%~88.3%,相对标准偏差(RSD)为3.9%~6.2%。该法净化效果好,灵敏度高,适于热带水果中杀虫双残留的快速定性和定量分析。

Abstract:

A method for the determination of bisultap in tropical fruits was developed by modified QuEChERS method and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The tropical fruit samples were twice extracted with acetonitrile containing 1% (v/v) acetic acid, and purified by 200 mg of primary secondary amine (PSA), 100 mg of C18, 300 mg of MgSO4 and 500 mg of disodium hydrogen citrate. The analyte was separated on a CAPCELL CORE PC hydrophilic column, detected in the negative ion multiple reaction monitoring (MRM) mode, and quantified by external standard method. A good linear relationship in the range of 0.1-10.0 μg/L was obtained with the correlation coefficient (r2) of 0.9993. The limit of detection and limit of quantification were 0.015 μg/kg and 0.05 μg/kg, respectively. The spiked recoveries were in the range of 81.0%-88.3% with the relative standard deviations from 3.9% to 6.2%. The method has good purification effect and high sensitivity, and is suitable for the rapid analysis of the bisultap residues in tropical fruits.
