| Abstract: | Objective：This paper established a method of ion pair chromatography for determination of melamine in baby formula. Methods：The separation was performed in Luna-Strong cation exchange column （4.6mm×250mm,5μm）with a mobile of acetonitrle- Phosphate acid （pH=3.0）=25：75.The flow rate was 1.2mL/min, and the detecting wavelength was at 240nm.Results：The linear ranges of melamine was 0.1673ug-0.8360ug, R=0.9999,respectively ;The average recoveries of melamine was 100.6%, RSD=0.91%, respectively. Conclusion： The method is simple and accurate with good reproducibility, and can be used for the quality control of Products. |
