  • Title: High pressure liquid chromatographic determination of nifursol in finished feeds.
    Author: George GM, Frahm LJ, McDonnell JP.
    Journal: J Assoc Off Anal Chem; 1981 Jul; 64(4):969-72. PubMed ID: 7275913.
    Abstract:
    Nifursol is extracted from feed with acetonitrile, and then washed with carbon disulfide to remove feed interferences. An aliquot is concentrated, diluted with 5% NaCl solution, filtered, and then subjected to high pressure liquid chromatography on a strong anion exchange column, using 365 nm photometric detection. The average recovery of nifursol from fortified feed samples was 100.6% with an average coefficient of variation of 3.5%. The nifursol determination is not subject to interference from the other commonly used nitrofurans.
