摘要： A high performance capillary electrophoresis (HPCE) has been developed for the determination of melamine residues in eggs. Test sample was extracted by trichloracetic acid, and the extract was further purified by SPE cartridge before it was detected by HPCE. The analyte was completely separated in a fused-silica uncoated capillary column (58.5 cm x 75 mu m i. d.) using 50 mmol/L formic acid-50 mmol/L ammonium formate (pH 2.5) within 6 min. The limit of quantification(LOQs) was 0.25 mg/kg, the average recoveries were in the range of 80.2%-90.6% with the spiked concentration of 0.25-5.0 mg/kg, and the RSD was between 1.7% and 3.4%.
