Abstract
The present invention includes an ion diffusion junction in an electrochemical cell. The junction includes a polymer matrix that is impermeable to the sample solution. A plurality of inclusions are disposed within the junction matrix and oriented to form continuous hydrolytic pathways extending between the sample solution and the reference electrolyte such that ion diffusion occurs along the hydrolytic pathways.
