  • Sensor for analysis of mixtures by global selectivity and its use in sensor system
    Publication number: 20040009585
    Abstract: The object of the present invention is to provide a means of detection and evaluation of mixtures, based on the concept of global selectivity, with enhanced sensitivity and selectivity. A first embodiment refers to a sensor for the analysis of mixtures by global selectivity comprising at least two sensor units consisting of: (a) interdigitated electrodes or microelectrodes sheathed with at least one monolayer of an ultra-fine film of a membrane forming material possessing physicochemical affinity for the substances peculiar to the mixture to be analysed selected from the group consisting of complexing polymer conductors, complexing substances and combinations thereof and, optionally, (b) non-sheathed interdigitated electrodes or microelectrodes.
