The presence of two of the metabolites of heroin, free morphine and morphine 3-beta-D-glucuronide (MO3G) in acidified urine samples was simultaneously determined by capillary zone electrophoresis (CZE). In a run buffer containing 50 mM sodium borate and 250 mM boric acid (pH 8.6), free morphine migrates before a group of neutral compounds (peak N) in urine… CONTINUE READING
