摘要
本实验研究了一种针对食品中非法添加苏丹红的分析方法,采用固相萃取技术对样品进行前处理,然后用HPLC对苏丹红样品进行分离,DAD和MS进行串联检测。提高了分析检测的准确性、可靠性。本方法灵敏度高,具有较高且稳定的回收率,精密度较好。分析应用结果令人满意。
A new analytical approach was discussed for detecting Sudan in food. Sample was pretreated by solid phase extraction. After separated with high performance liquid chromatography (HPLC),diode array detector (DAD)-tandem MS was used for detection to enhance the reliability of analytical results. The results showed that the pretreatment is efficient,and the analysis has high sensitivity and precision. Therefore,this new analytical approach is valuable in application.
