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.

摘要： An ion chromatographic apparatus and method for on-column preconcentration of trace ionic contaminants for quantitative trace analysis by ion chromatography. The method includes the multi-cycle, sequential steps of loading and purging of sample solution into and out of a sample injection loop to cumulatively preconcentrate a separator column with a cumulative amount of sample. Each purging step includes directing pressurized liquid, at a substantially constant rate and for a predetermined period of time to the sample injection loop, to drive up to about 98% of the known volume of the sample solution from the sample injection loop. In turn, this flushed volume of sample solution passes through an ion exchange resin column for concentration of the trace ionic contaminants in the resin.

摘要： A chambered ion reflux device for ion chromatography which electrolytically produces an eluent from a water pumped phase, suppresses the eluent and recovers (refluxes) the eluent ions for reuse. In the chambered ion reflux device, the eluent never passes through the electrode chambers. Since the eluent ions are refluxed and the eluent is produced electrolytically, the chambered ion reflux device can be used for isocratic or gradient ion chromatography. A chambered ion reflux device which integrates an electrolytic ion removal chamber is also disclosed.

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.
