Abstract
A method for measuring the activity of a component of a sample medium using a solid ion conductor having N components wherein N is less than or equal to 3 and having one component which corresponds to the component to be measured is disclosed. The process is carried out by first equilibrating the solid ion conductor with the medium and then with the N-2 adjacent phases of the phase system of the N components of the solid ion conductor. Finally, it is equilibrated with a reference electrode and the voltage between the reference electrode and the medium is measured.
