Automated high-performance liquid chromatographic method for the determination of a neuraminidase inhibitor (GG167) in human serum by pre-column fluorescence derivatisation using benzoin.
A pre-column fluorescence derivatisation high-performance liquid chromatographic method for the analysis of a neuraminidase inhibitor, GG167, in human serum is described. GG167 was extracted from serum samples using Bond Elut SCX solid-phase extraction cartridges, followed by derivatisation with benzoin prior to reversed-phase chromatography with fluorescence detection. This method has been automated using a Zymark robot and used in the analysis of human serum samples from clinical studies. The method has been shown to be valid over a concentration range of 10-800 ng/ml using a 1-ml sample volume.
