Voltammetric examinations of ferrocene on microelectrodes and microarrayelectrodes

Voltammetric investigations of ferrocene in organic media with planar, disk and band shaped microelectrodes (ME) and microarrayelectrodes (MAE) were carried out in stationary solutions and under flow-through conditions with flow-injection analysis (FIA). The electrodes were embedded in cylindrical electrode bodies made of epoxy resin. During the FIA experiments miniaturized flow-through cells with a three electrode configuration (wall-jet, thin-layer principle) were used. As detectors microelectrodes and microarrayelectrodes consisting of platinum wires (radius: 10 mu m), gold wires (radius: 12.5 mum), carbon fibres (radius: 3.5 mu m) and gold foils (foil thickness: 30 mum) were constructed using fine precision manufacturing methods by sealing the electrode materials in insulating resins.
