摘要：

The analytical method of melamine in milk and milk powder by high performance liquid chromatography (HPLC) was established. The sample was purified by a cation exchange solid-phase extraction column, separated on a Diamonsil C18 column (4. 6 mm x 200 rum, 5 mu m) with acetonitrile-0. 01 mol/L sodium heptanesulfonate (pH 3.3) (10: 90, v/v) as mobile phase at a flow rate of 1.0 mL/min, and determined by a photodiode array detector. A linear calibration curve was obtained in the concentration range of 1 - 500 mg/L. The qualification limit was 0. 2 mg/kg, and the quantification limit was 1 mg/kg. The recovery was 81.4% - 83.7%.
