Recent developments in new electrolytic devices that utilize the electrolysis of water and charge-selective electromigration of ions through ion-exchange media have significantly changed the routine operation of ion chromatographic methods. Examples of these new electrolytic devices include on-line eluent generators that produce high-purity electrolyte eluents using deionized water as the carrier stream, continuously regenerated trap columns that remove ionic contaminants in the eluents, and continuously regenerated suppressors that reduce eluent background conductance prior to conductivity detection. The combined use of these electrolytic devices has made it possible to perform various ion chromatographic separations using only deionized water as the mobile phase. This paper reviews the operation principles of these electrolytic devices and their applications in the ion chromatographic determination of anionic and cationic analytes.
利用水电解以及离子通过离子交换介质进行电荷选择性电迁移的新型电解装置的最新进展，显著改变了离子色谱方法的常规操作。这些新型电解装置的实例包括：使用去离子水作为载流产生高纯度电解质洗脱液的在线洗脱液发生器、去除洗脱液中离子污染物的连续再生捕集柱，以及在电导检测之前降低洗脱液背景电导的连续再生抑制器。这些电解装置的联合使用使得仅使用去离子水作为流动相来进行各种离子色谱分离成为可能。本文综述了这些电解装置的工作原理及其在阴离子和阳离子分析物的离子色谱测定中的应用。
