| Abstract_FL | Objective To develop a method for detecting six aflatoxins in chicken and pig liver. Methods Samples were extracted, filtered, concentrated and reconstituted purified by immunoaffinity column, derivatived aflatoxin G1, B1 using photochemical derivatization unit online after injection. Then six aflatoxins B1, B2, G1, G2, M1, and M2 were analyzed by fluorescence detector. Results The recoveries of samples with different spiking levels were 70.2%~94.1%. The RSD were 2.67%~12.90%. The lowest limit of quantification was 0.16 μg/kg. Conclusion This method is of high accuracy and precision, and can meet the requirements for trace analysis. |
