An apparatus and method for sensing time varying ionic current in an electrolytic system (2,2,2'') having a first fluid chamber (4,4', 104) and a second fluid chamber (8, 8'', 108) separated by a barrier structure 5 (11, 12', 111) is provided, wherein the barrier structure (11, 12', 111) includes thick walls (12, 112) and a substrate (14, 114) having an orifice (22, 22',122) therein, with the first (4,41', 104) and second (8, 8', 108) fluid chambers being in communication via the orifice (22,22', 122) A potential is applied between electrodes (18, 19, 118, 119) in respective first (4,4', 104) and second (8, 8', 108) fluid chambers, thus driving an electrical current between them and through the orifice (22,22', 122) Total capacitance of the system is less the 10 pF. |
