title: Liquid chromatographic determination of florfenicol in the plasma of multiple species of fish.
abstract: A simple method was developed for determining florfenicol concentration in a small volume (250 micro l) 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 (%RSD<or=8), and sensitivity (quantitation limit <30 ng/ml) of the method indicate its usefulness for conducting pharmacokinetic studies on a variety of freshwater fish.
