Anotace

V originále

Several designs of miniaturized electrochemical detectors based on incorporation of various types of microelectrodes into the ending of capillaries were developed. Capillary devices consisting of platinum teetrodes or free platinum and carbon microfibers were tested in biamperometric mode of operation. Detectors utilizing carbon or platinum microfibers as working and silver microwire as reference electrodes were used in amperometry of selected catecholamines. Analytical performance of different arrangements of microelectrodes in flowing streams was evaluated in the detection of dopamine in phosphate buffer carrier solutions and the detection limit as low as 110pg of dopamine on injection was attained
