Quantitation of Chloramphenicol and Nitrofuran Metabolites in Aquaculture Products Using Microwave-Assisted Derivatization, Automated SPE, and LC-MS/MS.

This paper describes a rapid and robust method utilizing microwave-assisted derivatization, automated SPE, and LC-MS/MS for the quantitation and confirmation of chloramphenicol (CAP) and nitrofuran metabolites in various aquaculture matrixes. The use of equipment presented in this work allowed extractions to be completed on average within 6 h, with quantitation accuracy ranging from 89 to 107% and RSD≤8.3%.
