摘　　要：采用高效液相色谱-串联质谱法建立了水体中稻瘟灵和吡唑醚菌酯的检测方法,以0.2%甲酸水溶液-甲醇为流动相,以电喷雾(ESI+)模式测定,多离子反应监测(MRM)模式扫描,外标法定量稻瘟灵和吡唑醚菌酯在0.000 1~0.05 mg/L均具有良好的线性关系,最低检测浓度分别为0.159μg/L和0.108μg/L。在0.000 2~0.02 mg/L进行添加回收试验,结果表明,2种有效成分平均回收率为82.86%~96.84%,相对标准偏差为2.14%~6.33%。The determination of isoprothiolane and pymclostrobin by ultra high performance liquid chromatography-electrospray tandem mass spectrometry （UPLC-MS/MS） was established. Using the 0.2% formic acid and acetonitrile as mobile phase, the sample was detected by ESI＋ in the MRM mode. The result showed that the calibration curves were linear, and and the limit of quantity were 0.159 μg/L and 0.108 μg/L, respectively. The average recoveries were 82.86% -96.84%, and relative standard deviations 2.14%--6.33 %.
