Analysis of Antibiotic Flumequine and Related Impurities in Mixed-Mode Chromatography

Chromatogram

Description

The antibiotic Flumequine is typically used in veterinary medicine. Flumequine and related impurities have been found in animals later sold for meat. Analysis was performed by by mixed-mode chromatography on Primesep D, a reverse-phase column with embedded basic ion-pairing groups and Obelisc R with multiple separation modes (RP,NP,IE).
