A DETECTION AND QUANTITATION METHOD FOR THERAPEUTIC AGENTS IN BLOOD

摘要

The present invention relates to an improved method for the determination of therapeutic agents in blood. This method utilizes a solid phase extraction of the solute from plasma followed by reverse phase high performance liquid chromatography on a column of irregularly shaped C-18 modified silica. Comparison of the produced chromatogram with a standard curve provides a precise and accurate quantification of the amount of the solute in blood. Additionally, the extraction and chromatography steps can be readily automated for the rapid determination of multiple samples.
