Originální abstrakt

The paper present new approach in the field of precise electrolytic conductivity measurements with planar sensors. This novel measuring method was suggested for measurement with IDEs thick-film electrodes. Correction characteristics over a wide range of a specific conductivities were determined from an interface impedance characterisation of the thick-film IDEs. A local minimum of the imaginary part of the interface impedance is used for corrections to get linear responses. The ridge frequency was determined at wide range of measured conductivity. An iteration mode of measurements was suggested to exactly measure the conductivity in the ridge frequency in order to achieve a highly accurate response. The method takes precise conductivity measurements in concentration ranges from 10-6 to 1 M without cell replacement.
