| 摘 要： | 目的建立适用于鸡蛋中氟虫腈及其代谢物(氟虫腈砜、氟虫腈硫醚和氟甲腈)残留的电子捕获检测器-气相色谱法和高效液相色谱-串联质谱检测方法。方法通过Qu ECh ERS提取盐包(CEN EN-15662)用乙腈提取目标化合物,借助固相萃取(PRiMEHLB)作为净化手段,采用气相和液相质谱进行监测。结果气相色谱法和高效液相色谱-串联质谱法中4种分析物的定性限(limit of detection,LOD)分别为0.1μg/kg和0.02μg/kg;定量限(limit of quantification,LOQ)分别为0.5μg/kg和0.1μg/kg,在0.1~10.0μg/L和0.1~5.0μg/L范围内线性关系良好,相关系数r~2均大于0.999。在2.5,5和10μg/kg 3种加标浓度下,平均回收率分别为80.8%~103%和87.4%~101%,相对标准偏差(relative standard deviation,RSD,n=6)分别为0.84%~5.62%和0.87%~4.40%。结论该方法步骤简便、可靠、稳定,适合于蛋类中氟虫腈及其代谢物残留的痕量分析。
