摘  要:
本文建立了生姜中丙炔氟草胺残留量的分析方法。试样经乙腈提取,活性炭柱净化,目标农药采用气相色谱-质谱/选择离子监测法(GC-MS/SIM)进行定性、定量分析,方法检出限为0.006mg/kg,在0.02、0.04、0.05、0.1、0.2mg/kg添加水平回收率为62%~105%,相对标准偏差(RSD)5.2%~18%。

摘  要:
Flumioxazin was extracted from sample with acetonitrile and the extract was cleaned up by using SupelcleanTMENVITM- Carb SPE Tube (0.5g, 6ml). The final extract was injected into GC, followed by MS detection under EI ionization and selective ion monitoring mode. The detection limit was 0.006mg/kg. Precision and recovery tests were made at the spike level of 0.02, 0.04, 0.05, 0.1, 0.2mg/kg, and the results were as follows: recoveries in the range of 62%~105%, relative standard deviation 5.2%~18%.
