Potentiometric sensor comprising a reference electrode and at least one ion-selective electrode for use in an electrochemical analysis of an aqueous sample, comprising
an electric conductor;
an insulating layer on the conductor, the insulating layer having a throughgoing aperture defining an electrode region; and
a heterogeneous membrane layer on the insulating layer in the electrode region for direct contact with the sample and for electrical contact with the conductor through the aperture, the heterogeneous membrane layer having at least one hydrophobic, gas permeable compartment and at least one hydrophilic ion conducting electrolyte compartment, characterized in that the conductor is one of an array of n metallic conductors, and the insulating layer has n throughgoing apertures, each defining an electrode region and being located over one of the metallic conductors and that the heterogeneous membrane layer is one of n membrane layers respectively contacting one of the n metallic conductors. |
