Abstract
A separation column for separating and developing a sample to be analyzed is connected to a pump for feeding an eluting solution at an end of the separation column. A means for introducing the sample to be analyzed is provided between the pump and the separation column. Another end of the separation column is connected to an electrochemical detection means through a mixing means. To the mixing means is connected a pump for feeding a catalyst solution capable of promoting an electrode reaction of the sample contained in an eluate solution. A mixture solution of the eluate solution and the catalyst solution from the mixing means is fed to a detection means to quantitatively determine the sample.
