Determination of nifursol in medicated animal feeds using high-performance liquid chromatography

Abstract

A method is given for the determination of nifursol in medicated animal feeds by high-performance liquid chromatography. The additive is extracted from the feed sample into acetonitrile and this solution is concentrated by evaporation of acetonitrile under reduced pressure. The nifursol content of this solution is determined by HPLC using a column containing a strong anionic-exchange packing.
