| 摘 要： | method for determination of melamine residue in fishery products by liquid chromatography-mass spectrum （LC-MS/MS）was established. The conditions of LC-MS/MS was optimized. The sample was ultrasonically extracted with 1% triehloroactic acid and ethylamine, and cleaned by the solid phase extraction （MCX） cartridge. The analyte was identified by electrospray ionization （ESI） in positive mode using multiple reaction monitoring （MRM）. The determination ion pairs are 127/85 and 127/68,and the confirmation ion pairs are 127/85. The method was validated and good results were obtained with respect to spiked recoveries. The linear range was from 10 to 400 ng/mL,the average recoveries were between 80.5%and 94.1% in the spiked rang of 0.01 -10.0 mg/ kg. LOQ was 0.01 mg/kg.
