Abstract: AN ELECTROCHEMICAL ELECTRODE ASSEMBLY INCLUDES A HOUSING DEFINING AN ELECTROLYTE CHAMBER. THE HOUSING HAS AN APERTURE IN A WALL AND A SELECTIVELY PERMEABLE MEMBRANE IS DISPOSED ACROSS THE APERTURE. AN ELECTRODE IS SUPPORTED WITHIN THE CHAMBER IN CLOSE PROXIMITY TO THE MEMBRANE AND A FILTER IS SUPPORTED ON THE HOUSING AND INTERPOSED BETWEEN THE MEMBRANE AND TEST MATERIAL IN SPACED RELATION TO THE MEMBRANE TO INTERCEPT LIQUID PARTICLES WHILE FREELY PASSING GAS FROM THE MEDIUM.

Abstract: An electrochemical analyzer includes a cathode electrode, an anode electrode, and electrolyte in the space between them. A selectively permeable membrane is disposed over the cathode electrode and in turn is covered by a porous hydrophobic membrane. The porous membrane has a substantially greater area than that of the cathode, and allows substantially unimpeded gaseous flow through it in both the lateral and longitudinal directions.
