Vue, C., Schmidt, L. J., Stehly, G. R., and Gingerich, W. H., 2002, Liquid chromatographic determination of florfenicol in the plasma of multiple species of fish: Journal of Chromatography B Analytical Technologies in the Biomedical and Life Sciences, v. 780, no. 1, p. 111-117. Abstract A simple method was developed for determining florfenicol concentration in a small volume (250 mul) of plasma from five phylogenetically diverse species of freshwater fish. Florfenicol was isolated from the plasma matrix through C-18 solid-phase extraction and quantified by reversed-phase high-performance liquid chromatography with UV detection. The accuracy (84-104%), precision (%RSDless than or equal to8), and sensitivity (quantitation limit <30 ng/ml) of the method indicate its usefulness for conducting pharmacokinetic studies on a variety of freshwater fish.
