| 摘 要： | 针对目前动物产品中兽药残留检测样品前处理繁琐的问题,应用全自动固相萃取技术对动物产品中9种磺胺类药物残留检测的样品前处理方法进行了系统的研究,对提取溶剂、固相萃取柱、淋洗液、洗脱溶剂及仪器分析条件进行了优化选择,建立了新型磺胺药物残留检测的全自动固相萃取净化方法.经不同检测单位验证,该方法的加标回收率为78.4%～107.8%,精密度为3.9%～11.0%检出限为0.010～0.020mg/kg,满足出口检测要求.

| Abstract: | The sample pretreating method applying automatic solid phase extraction technique in determinating sulfonilamide residue in animal products was systematiclly studied. Many influencing factors such as extracting solvent, solid phase extraction column, washing liquid, eluting solvent and apparatus analyzing condition were optimized. A new cleansing method of determining sulfonilamide residue was built. The method was verified by different departments with recovery rate 78.4% - 107.8% , precision 3.9% - 11.0% and determination limit 0. 010 -0. 020 mg/kg, which can meet export testing requirements. |
