Abstract
A submicroliter electrochemical detector for liquid chromatography has been designed, using pressure-annealed pyrolytic graphite technology. The analytical performance of this detector was studied in connection with a reversed-phase packed microcapillary column at very low flow-rates. Although the miniaturized version of the electrochemical detector is less sensitive, a direct analysis of a number of urinary metabolites in 0.1--1.0 microliters samples is feasible.
