A LC-ESI-MS/MS method for determining chloramphenicol residues in fish, shrimp, poultry, eggs, bovine and swine was developed and validated. The samples were extracted with a phosphate extraction solution followed by liquid-liquid extraction with ethyl acetate. The LC was performed on a C18 column at room temperature. For all the matrices, the analytical curves showed r values and recoveries higher than 0.99 and 50%, respectively. The accuracy values lay between 85 and 120% and the precision was lower than 20%. The LOQ was 0.1 ng/g. The method was employed to analyze samples collected in Brazil.
建立并验证了一种测定鱼、虾、禽肉、禽蛋、牛和猪组织中氯霉素残留的 LC-ESI-MS/MS 方法。样品经磷酸盐提取液提取后，再用乙酸乙酯进行液-液萃取。LC 分析在室温下于 C18 柱上进行。对于所有基质，分析曲线的 r 值和回收率均高于 0.99 和 50%。准确度值在 85%至 120%之间，精密度低于 20%。LOQ 为 0.1 ng/g。该方法用于分析在巴西采集的样品。
