METHOD AND SYSTEM FOR DETECTING CHLORAMPHENICOL

摘要

Methods and systems for detecting drugs, particularly amphenicols such as chloramphenicol, in samples such as honey and other foods, are described. An aspect includes a method and system for separating chloramphenicol from compounds that could interfere with an immunoassay for detection of chloramphenicol. In one aspect, chloramphenicol is extracted from the sample by buffering the sample and eluting the sample from a solid phase extraction column with a cyclohexyl functional group. The eluent is tested for the presence of chloramphenicol. False positive results are avoided by using mild organic solvents and a solid phase extraction column to separate interfering substances from the substances to be tested.
