近期,湖南化工研究院有限公司科研人员采用高效液相色谱—串联质谱(LC—MS/MS)方法,分析了戊唑醇和吡唑醚菌酯在玉米植株和土壤中的残留及消解动态。其中土壤样品采用乙腈提取,植株样品采用乙腈和丙酮提取,过膜后采用LC—MS/MS分析。结果表明:戊唑醇和吡唑醚菌酯在土壤和玉米植株中的定量限分别为0.01、0.02mg/kg,检出限分别为 Recently, Hunan Chemical Research Institute Co., Ltd. researchers using high performance liquid chromatography-tandem mass spectrometry (LC-MS / MS) method analysis of tebuconazole and pyraclostrobin residues in corn plants and soil dynamics and digestion. The soil samples were extracted with acetonitrile. The plant samples were extracted with acetonitrile and acetone, and analyzed by LC-MS / MS after passing through the membrane. The results showed that the limit of quantification of tebuconazole and pyraclostrobin in soil and corn plants were 0.01,0.02mg / kg, the detection limits were
