| Abstract: | A Method for the determination of melamine with non-derivative GC-MS/MS in dairy prod ucts is introduced. The sample is extracted with acetonitrile water solution, cleaned up with MCX col umn and then determined by GC-MS/MS using multiple reaction monitoring （MRM） scan mode. The results show that the working curve is linear in the range of 0-10 mg/kg. The limit of detection （IX）D） of melamine is 0. 005 mg/kg. Extraction recoveries for melamine range from 88.7% -- 100.6% and RSD is between 2.7%-8.6%. The method is suitable for the determination of melamine in clair y products. |
