Determination of nitrofuran metabolites residues in animal derived food by UPLC-MS/MS
This study established the determination of nitrofuran metabolites residues in animal derived food by ultra pressure liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The detection limits of four kinds of nitrofuran metabolites were 0.25 μg/kg and the linear range was between 0.5~10.0 μg/L, the recovery rates were 81.6%~97.3%, the RSD were less than 10%. The method is rapid,simple,precise, sensitive and suitable for determination of nitrofuran metabolites residues in animal derived food.
