Abstract
A sample leaving a separation column of liquid chromatograph is led to an electrolytic cell to obtain an electrolytic current corresponding to the amount of an assayed sample component. The electrolytic cell is divided into two compartments by an ion exchange pipe penetrating therethrough at the center. One compartment is a cylindrical working electrode chamber in the pipe, and the other compartment is a cylindrical chamber for a counterelectrode outside the pipe. A working electrode comprising a bundle of electroconductive carbon fibers is provided in the working electrode chamber, and preferably a swellable rod is inserted as a core into the working electrode. In the chamber for the counterelectrode, a cylindrical counterelectrode made of carbon fibers is provided to surround the outside surface of the ion exchange pipe. The inner diameter of the ion exchange pipe is substantially equal to the inner diameter of a tube for introducing the sample. The sample undergoes electrolysis reaction while the sample passes through the carbon fibers of the working electrode.
