Recently many chemical sensor applications use the thin film technology. Electrode system has had a comb structure. These systems are called interdigitated electrodes (IDES). In most cases good results were achieved using differential or transient measurements. Measurement of frequency characteristics is not possible without correction of cell constant, which is different of the real cell constant. Results of our current research show many problems with the behavioural of chemical cells if the electrode distance is decreased below 1 mm. The cell starts to change its impedance and cell work place is lifted to high frequency. We suppose that both the distance and the shape of IDES influence the frequency characteristic. If the thin-film technology is used for producing IDES, a large resistance is added into results. Our work is based on modelling of a cell behaviour close to electrode and a potential distribution on electrodes
