Originální abstrakt

A sensor miniaturization brings many problems e.g. an effect of the double layer capacitance, a serial resistance of electrodes, a cell constant etc. First results indicate different behaviour of the small-sized electrodes in comparison with the standard large ones. Conductivity measurements need corrections of the cell constant for each type of a liquid solution. Variation of a cell size shows possibilities to find cross relations of all factors. In summary, it is obvious that the Faraday impedance changes character, it means cut-off frequencies of the total impedance frequency characteristics are shifted under a condition variation of measurements. In addition, Wien effect can display for a small inter-electrode distance because high voltage field rises across electrodes as the inter-electrode distance decreases.
