| Abstract: | A gas chromatography time-of-flight mass spectrometry for determination of FF(florfenicol,FF)and FFa(florfenicol amine,FFa)residue in egg was established.The samples were extracted with alkalized ethyl acetate.The detection was carried out by gas chromatography time-of-flight mass spectrometry.Good linear relationship was obtained in the concentrations of 2-100 ng/mL,while the correlation coefficient of FF was 0.999 and FFa was 0.998.The detection limit of this method was 5μg/kg.The recoveries at three spiked levels(0.5,1.5 and 10.0μg/kg)were in the range of 86.4%-119.4%with RSDs(n=3)between 2.9%and 7.1%.The method was simple,rapid,sensitive and accurate to meet the needs of the analysis,which could be used for the detection of FF and FFa residue in eggs. |
