Study on the Determination of Chloramphenicol Residues in Honey by Liquid Chromatography-Mass Spectrometry/Mass Spectrometry
The method for determining chloramphenicol residues in honey using liquid chromatography-mass spectrometry/mass spectrometry was established.Honey samples were extracted with ethyl acetate,purified using an EN solid phase extraction column,concentrated by nitrogen blowing,and analyzed by liquid chromatography-mass spectrometry/mass spectrometer using internal standard method.The results showed that the linear relationship of chloramphenicol was good,with a detection limit of 0.04 μg·kg-1 and a limit of quantitation of 0.1 μg·kg-1.The recovery rate was within the range from 89.5％to 104.1％,and the relative standard deviation was 2.98％to 3.86％,which can meet the regulatory detection of chloramphenicol residues in honey.
