건립료고효액상색보법-천련질보법검측남미백대하중을양기규람잔류적방법。정기완제취목표분석물,채용C18색보주진행분리、질보진행분석,보취간단방편。본방법침대남미백대하기육조직적검측하한위5μg/kg,선성범위：5～50μg/kg。3수평첨가회수솔위80%～90%,상대표준편차0.53%～2.19%。
A method for analysis of trace ethoxyquin residues in Penaeus vannamei was developed by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Hexane extraction of target analytes,using a C18 column separation,mass spectrometry,the process was simple and convenient.The lower limit of this method was 5 μg/kg,and the linear range was 5~50 μg/kg.The recoveries in three spkied level were in the range of 80%~90%,with relative standard deviation(RSD)of 0.53%~2.19%.
