Abstract:

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.

Key words: Sudan, HPLC/DAD/MS, analysis
