| 摘 要： | 为评价和维护农产品的质量安全，采用离子阱质谱建立50 余种农药的液相色谱- 质谱数据库，通过谱库检索技术可以实现农产品中未知农药组分的快速筛选及定性。在对未知组分进行谱库检索后，通过LC-DAD-MS/MS 方法比较未知组分与标准样品的保留时间、二级质谱的萃取离子流色谱图(EIC)以及紫外光谱图，得到确认结果。采用本实验所建立的未知组分定性方法对实际样品中的未知污染物进行快速筛选，确认了实际样品中所残留的农药污染物。

| Abstract: | In order to assess and maintain the quality safety of agricultural products,a liquid chromatography-tandem mass spectral database was constructed for more than 50 pesticides using ion-trap mass spectrometry,which was helpful to rapid selection and qualification of unknown pesticides in agricultural products by database searching.The qualification of unknown pesticides could be achieved by aligning their retention time,MS/MS extracted ion current chromatogram,UV absorption spectrum with those of standard sub... |
