Iterative Method of Measurements for Chemical sensors

Popis výsledku v původním jazyce

The paper contributes to 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. The cell constant strongly depends on the frequency and conductivity of solutions. A local minimum of the imaginary part of the interface impedance is uused for corrections to get linear responses. In this minimum a ridge frequency and cell constant were determined for each 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. An implementation of this method as a microcontroller application can used to build-up microsystem for precise conductivity measurements in concentration ranges from 10-6 to 1 M without cell
