The present invention relates to a method of automated measuring electrochemical signals on several sets of electrodes, wherein each electrode set comprises a measuring, a reference and optionally also an auxiliary electrode. The invention is characterized in that, potential or current signal is applied in a selected sequence to the electrode sets and the measured electrochemical signals are then gradually sensed in that selected sequence. The invention also relates to an apparatus for making the above-described method, the apparatus comprising a control computer (1), comprising a control and evaluation software (2), connected to a D/A converter (3), having its outputs connected to a potentiostat (4) or a galvanostat (5), which are connected to a multiplexer (6) having its contact parallel connected to the sets of electrodes (S1 to Sn). Current output of the multiplexer (6) is connected to a current-voltage converter (7) that is connected to the sensitivity control circuits (8). The output of the sensitivity control circuits (8) is then applied to an amplifier (9), while voltage outputs of the multiplexer are applied directly to the amplifier (9). The amplifier (9) output is applied to the A/D converter (3), and the output of the A/D converter (3) is applied to the control computer (1). |
