Abstract | PURPOSE:To perform the measurement corresponding to the reversibility or non- reversibility of the electrolytic reaction of an objective substance by constituting one set of a detector of an acting electrode cell and a reference electrode/opposed electrode cell to arrange two or more sets of detectors in series and continuously passing a solution through the detectors to detect the reducing current thereof. CONSTITUTION:Fixed blocks 1, 2 have liquid passing pipe connection ports 1a, 2a and the respective ports have liquid passing ports 1b, 2b having outer diameters opened to the internal end surfaces thereof. Channel holes 6 each having the same caliber as each of the liquid passing ports 1b, 2b are formed to respective acting electrodes 3a, 3d on the respective axes of center holes 5 and opposed electrode main body cells 4a, 4d. By this constitution, a liquid passage composed of the repeating arrangement of the center holes 5 and the channel holes is formed between the liquid passing ports 1b, 2b. An opposed electrode main body 4 has the reference electrode 8 communicating with the channel holes and a reference electrode 14 is inserted therein. An opposed electrode terminal 5 is inserted in a terminal hole 16. The inlet 1 of this detector is connected to a liquid chromatograph to allow a solution to pass through the detector to detect a reducing current. |
