摘要:

采用超高效液相色谱- 电喷雾串联四极杆质谱仪(UPLC-ESI-MS-MS),在多反应监测(MRM)模式下建立测定9 种基质中甲基碘磺隆农药残留的定性定量分析方法。选择苹果、菠菜、葱、小麦、黄豆、牛肉、鸡肝、脂肪、牛奶为空白样品基质,样品使用有机溶剂超声提取,凝胶渗透色谱(GPC)净化。本方法简便、快速、灵敏,方法的线性范围、回收率、精密度和检出限均符合残留分析的要求。

Abstract:

A method of UPLC-MS-MS in multiple reaction monitoring (MRM) mode was developed for the qualitative and quantitative analysis of iodosulfuron-methyl-sodium in 9 substance including apple, spinach, shallot, wheat, bean, beef, chicken liver, fat and milk. The sample preparation was based on ultrasonic-assisted organic solvent extraction and GPC cleanup. The results showed that the method developed is easy, rapid and sensitive, and all of its linear range, recovery, precision and detection limit meet the requirement of residue analysis.

Key words: UPLC-MS-MS, iodosulfuron-methyl-sodium, pesticide residue
