Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for continuous electrochemically suppressed ion chromatography and to provide an apparatus used for the method. SOLUTION: A chromatography effluent which contains sample ions and an electrolyte is divided into the flow of a first chromatography effluent and the flow of a second chromatography effluent. Electrolysis ion water which is selected from a group composed of hydronium ions and hydroxide ions is generated by the electrolysis of water. The electrolysis ions whose electric charge is identical to that of the electrolyte and the flow of the second chromatography effluent are made to flow through a stationary phase. Thereby, the electrolyte in the flow of the second chromatography effluent is suppressed. The sample ions are then detected in the flow of the second chromatography effluent which is suppressed.
