Method for the confirmation of chlorophenols in human urine by LC with an electrochemical detector

A method is described for the confirmation of chlorophenols in human urine. A hydrolyzed urine sample is analyzed by both gas chromatography (GC), and liquid chromatography (LC) with electrochemical detection and the results compared. A discussion of these results, including factors affecting separation, detection, and confirmation of chlorophenols in human urine, is included.
