Determination of dopamine and methoxycatecholamines in patient urine by liquid chromatography with electrochemical detection and by capillary electrophoresis coupled with spectrophotometry and mass spectrometry

The applicability of capillary electrophoresis (CE) with UV and mass spectrometric (MS) detection for the determination of dopamine and methoxycatecholamines in urine was evaluated in comparison with the liquid chromatography–electrochemical detection (LC–EC) method widely used in catecholamine anal...
