eng	Microelectrode Detectors for Miniaturized Flow Systems with Enhanced Sensitivity	Carbon fiber and silver microwire were used as working and pseudoreference electrode, respectively, to design an electrochemical detector integrated into monolithic capillary column. To further increase sensitivity of developed electrochemical microdetector, multiple pulse amperometric detection mode has been used. Optimized integrated device provided reliable chromatographic separation of mixture of neurotransmitters with calibration curve for dopamine linear from 0.5 to 20.0 mg L−1 and an instrumental limit of detection as low as 24 pg of injected dopamine.
