Chloramphenicol is an antibiotic and one of the potential contaminants in honey.Solid-phase extraction is the key pretreatment procedure for analysis of chloramphenicol in honey.In this work,an on-line pretreatment liquid chromatography-tandem mass spectrometer system for sensitive,reliable and higher throughput analysis was developed.With the methylcellulose-immobilized reversed-phase column,sugars in a honey sample were efficiently removed in 1 min.As a result,the limit of quantitation of chloramphenicol was 20 pg/mL(0.2 μg/kg honey).
Chloramphenicol is an antibiotic and one of the potential contaminants in honey. Solid-phase extraction is the key pretreatment procedure for analysis of chloramphenicol in honey. In this work, an on-line pretreatment liquid chromatography-tandem mass spectrometer system for sensitive, reliable and higher throughput analysis was developed. Based on methylcellulose-immobilized reversed-phase column, sugars in a honey sample were efficiently removed in 1 min. As a result, the limit of quantitation of chloramphenicol was 20 pg / mL (0.2 μg / kg honey) .
