Electrochemical analysis system, which comprises disposable analysis elements (10) and an evaluation device (20). The analysis elements (10), in a sample infeed area (12), have a working electrode (13) and a reference electrode (14). In a terminal area (19) there are terminal contacts (17) which are connected to the electrodes via connection lines (16). The evaluation device has an analysis element terminal with appliance contacts (21) for the electric connection to the terminal contacts of the analysis elements. …<??>Improved reliability and accuracy of the analysis with relatively little effort is achieved in that the measurement and evaluation circuit (23) has a switchover device (51), via which an electric voltage source (45) having a current-measuring device (52, 43, 49) and a voltage-measuring device (41, 39) can optionally be connected to various terminal contacts (17a-17d) of the analysis element (10). …<IMAGE>… |
