A high-pressure liquid chromatographic system for the separation of UV-absorbing and/or fluorescent urinary metabolites is presented. Thirty to forty UV-absorbing chromatographic peaks are obtained from a 200-microliters urine sample using a 100 cm x 2 mm column filled with a total porous ion-exchanger. The reproductibility of the separation has been studied and eighteen important substances have been located.
