PROBLEM TO BE SOLVED: To provide an electric conductivity detector which has a good output linearity for an ion concentration contained in liquid eluted from a separation column and whose measuring cell capacity is small.SOLUTION: The electric conductivity detector includes two working electrodes arranged in parallel, two measuring electrodes arranged so as to be parallel to and sandwiched by the two working electrodes, an insulator for filling a space between the two working electrodes, a channel which is arranged so as to contact with the two working electrodes and the two measuring electrodes and brings the liquid to flow therein, and a measuring cell which brings current flowing into/out of the measuring electrodes to be extremely small, thereby solving the problem. |
