Abstract
(EN)
This electrical conductivity detector is provided with at least: a cell unit, which has a cell wherein a liquid is circulated, and measuring electrodes for measuring a current flowing in the cell; a detection circuit that is configured such that the detection circuit is electrically connected to the measuring electrodes, and that the detection circuit detects the value of a current flowing between the measuring electrodes, and outputs a signal based on the detection value; and a processing unit that is configured to fetch the signal outputted from the detection circuit, and perform signal processing. The cell unit and the detection circuit are configured to be housed in a column oven that is provided for the purpose of adjusting the temperature of the analytical column of ion chromatograph.
