    摘要: The present invention pertains to a method of ion chromatography wherein a specialized electrodeionization (EDI) apparatus is used for (1) the preparation of a pure acid or pure base for use as an eluent in a chromatographic separation column and/or (2) for ion suppression (or neutralization) of the acid or base after it has been used to elute ions from a chromatographic separation column. Methods for trace ion removal, acid and base neutralization, and ion suppression using a specialized EDI apparatus are also described. The methods described herein allow for the ion suppression of samples containing chloride, nitrate, and other electrochemically active anions, without causing damage to the suppressor.

    摘要: Electrolytic eluent recycle systems for ion chromatography using a multi-channel electrolytic ion exchange device which integrates suppression, eluent generation, and eluent recycle. The systems recycle the eluent into the analytical system without passing the eluent through the electrode chambers. Also, such systems with a channel for electrolytic removal of ions from the suppression effluent before recycle.

    摘要: For anion analysis, the method includes: (a) flowing an aqueous liquid sample stream containing anions to be detected and cation hydroxide through a separator bed, (b) flowing the aqueous effluent from the separator bed through a flow-through suppressor, (c) flowing the effluent liquid from the suppressor past a detector, (d) recycling said liquid effluent from the detector through a cathode chamber proximate to the suppressor bed and separated by a first barrier, and (e) applying an electrical potential between the cathode and the anode. Water is electrolyzed at the anode to cause cations on the cation exchange resin to electromigrate toward the barrier and to be transported across the barrier toward the cathode while water in the cathode chamber is electrolyzed to generate hydroxide ions which combine with the transported cations to form cation hydroxide in the cathode chamber.
