✦ Synopsis
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.
