After centrifugation, the extracts were separated on HILIC column by using acetonitrile-water as mobile phase. The analytes were identified and quantitated by LC-tandem MS under the positive/negative electrospray ionization and multiple reaction monitormode. The calibration curves showed good linearity in the range of 25-5000 μg/kg for melamine and cyanuric acid, and 50-10000 μg/kg for ammeline and ammelide. The limits of detection and limits of quantification were in the range of 5-20 μg/kg and 50-100 μg/kg, respectively.
