Abstract: An electrode assembly includes an elongated tubular support member to which is secured a coupling structure. An electrode structure is supported by the coupling structure and has a sensing surface that projects externally of the coupling structure. A housing structure has a selectively permeable membrane secured over an opening at one end so that a chamber is defined for receiving an electrolyte solution. The housing is connected to the coupling structure so that the exposed sensing surface of the electrode structure is disposed in the electrolyte structure with its sensing surface in contact and distorting the membrane structure. The housing and coupling structures have cooperating engaged locating surfaces that define the amount of permitted distortion of the membrane structure.

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.

Abstract: An electrochemical electrode system includes a first chamber adapted to contain electrolyte and a second chamber adapted to contain the material to be analyzed. An opening is associated with each chamber and the openings are in juxtaposed relation to one another. The system further includes a flow control member that has a plurality of porous flow control sections of identical characteristics connected together for sequential positioning between the two openings. The member is movable to replace one section by another section between the openings, and structure is provided for sealing the two openings to the flow control section in position between the openings.

Abstract: ANALYSIS CHAMBER CLAMPS THE SELECTIVELY PERMEABLE MEMBRANE AGAINST THE EXTERNAL SURFACE OF THE STEM.
ELECTROCHEMICAL APPARATUS INCLUDES AN ELECTODE ASSEMBLY HAVING AN ELECTROLYTE CHAMBER WITH A PROJECTING STEM PORTION. A PH SENSITIVE MEMBRANE IS SECURED ACROSS THE END OF THE PROJECTING STEM PORTION AND A SELECTIVELY PERMEABLE MEMBRANE IS SECURED OVER THE PH SENSITIVE MEMBRANE. THE ELECTRODE ASSEMBLY IS DISPOSED IN AN ANALYSIS CHAMBER SO THAT THE PH SENSITIVE MEMBRANE IS ENTIRELY WITHIN THE ANALYSIS CHAMBER. A CLAMP AT THE PORT OF THE
