Abstract:A method for identification and qualification of Chloramphenicol, Florfenicol and Thiamphenicol residues in aquatic product was developed with the internal standard method and micro pre-processing method, which could avoid the solid phase extraction steps. The limit of quantization (LOQ) of Chloramphenicol, Florfenicol and Thiamphenicol residues were 0.05 ng/mL, 0.5 ng/mL and 0.7 ng/mL, respectively, with a recovery ranged from 80 to 120%. And the corresponding concentration of the three compounds were within range of 0.05~1.2 ng/g, 0.5~20.0 ng/g and 0.7~28.0 ng/g, respectively, showing a good linear relationship between peak area ratios and correlation coefficient. The method were simple, fast and efficient, which can meet the needs of determination and quantization of related compounds in aquatic foodstuffs.
