High-performance liquid chromatographic determination of penicillamine in whole blood, plasma, and urine

A high-performance liquid chromatographic method for the determination of penicillamine in plasma, whole blood, and urine samples is described. The method uses a commercially available electrochemical detector at a potential of +0.1 V versus the Ag/AgCl reference electrode. This method is selective and sensitive for sulfhydryl compounds. The chromatography separates penicillamine from other endogenous sulfhydryl compounds with a limit of detection for penicillamine in biological samples of ca. 10-7 M.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24427/1/0000698.pd
