| Abstract: | Objective] To establish a LC-MS-MS method for the determination of three kinds of polyether residues in eggs by QuEChERS dSPE EMR-Lipid as a pre-treatment using Agilent Bond Elut enhanced lipid removal EMR-Lipid technology.Method] Egg was extracted by acidified acetonitrile,purified by Bond Elut EMR-Lipid QuEChERS,and detected by HPLC-MS-MS.Resul] There was a good linear relationship between the three kinds of polyether residues in the range of 2.0-100.0μg/L,r ＞0.999.The recoveries ranged from 84.6％ to 107.0％.Conclusion] The method is convenient and accurate,and the quantitative results are accurate and reproducible.It is suitable for the determination of three kinds of polyether residues in eggs. |
