Abstract (en)

[origin: WO0142774A2] A microfabricated potentiometric sensor and a method of measuring the activity of analyte ions in a sample solution, the sensor comprising: a substrate chip; a flow channel defined by the substrate chip through which analyte ions of a sample solution are in use driven; at least one ion-selective electrode comprising a chamber defined by the substrate chip and including a port in communication with the flow channel, an ion-selective membrane disposed in the chamber, and a conductive element configured such as in use to be in electrical connection with the ion-selective membrane; a reference electrode configured such as in use to be in electrical connection with the flow channel; whereby, on driving analyte ions of a sample solution through the flow channel, an electromotive force is developed between the at least one ion-selective electrode and the reference electrode which is representative of the activity of the analyte ions.
