Boron doped diamond microelectrodes arrays for electrochemical detection in HPLC.

Boron doped diamond microelectrodes arrays (MEA) have been prepared in order to be used as new amperometric sensors in electrochemical cells for HPLC detectors. The following parameters were studied: number and diameter (15-40 µm) of the electrodes, distance between them (50-240 µm), and effect of the flow rate (0.1-3 mL/min).
