Abstract:
An electrochemical sensor comprising:a first member including a first surface;a second member including a second surface at least partially defining a cavity the first member being sized to fit into the cavity of the second member to form an electrolytic chamber between the first surface of the first member and the second surface of the second member;a non-porous electrolytic junction formed of an ion permeable member closing the electrolytic chamber and separating the electrolytic chamber from the process solution; anda wickless helical channel along a portion of the electrolytic chamber formed between the first and second members, wherein a portion of one of the first and second surfaces includes a helical surface structure, the first and second members being sized so that the helical surface structure tightly engages a generally smooth surface of a portion of the other of the first and second surfaces to form the wickless helical channel being between the first and second surfaces.
