    • Method and apparatus for generating an acid or base, e.g. for chromatographic analysis of anions. For generating a base the method includes the steps of providing a cation source in a cation source reservoir, flowing an aqueous liquid stream through a base generation chamber separated from the cation source reservoir by a barrier (e.g. a charged membrane) substantially preventing liquid flow while providing a cation transport bridge, applying an electric potential between an anode cation source reservoir and a cathode in the base generation chamber to electrolytically generate hydroxide ions therein and to cause cations in the cation source reservoir to electromigrate and to be transported across the barrier toward the cathode to combine with the transported cations to form cation hydroxide, and removing the cation hydroxide in an aqueous liquid stream as an effluent from the first base generation chamber. Suitable cation sources include a salt solution, a cation hydroxide solution or cation exchange resin.
    • 用于产生酸或碱的方法和设备,例如, 用于阴离子的色谱分析。 为了产生碱,该方法包括以下步骤:在阳离子源储存器中提供阳离子源,使水性液体流通过基本上防止液体流动的屏障(例如带电膜)与阳离子源储存器分离的碱性产生室流动, 提供阳离子输送桥,在基底产生室中的阳极阳离子源储存器和阴极之间施加电位以在其中电解产生氢氧根离子,并使阳离子源储存器中的阳离子电迁移并穿过屏障向着 阴极与所运送的阳离子结合以形成阳离子氢氧化物,并且以水溶液流中的阳离子氢氧化物作为来自第一碱基产生室的流出物除去。 合适的阳离子源包括盐溶液,阳离子氢氧化物溶液或阳离子交换树脂。
