摘要：

A dual-column technique for the simultaneous analysis of anions and cations is described. The technique involves the use of the conventional ion chromatography equipment with the addition of a switching valve. Two columns (an anion and a cation column) are used as the separator columns. By using an eluent that contains both anion and cation driving ions. the simultaneous separation of anions and cations can be accomplished with one injection. one pump, and one detector. Two eluents are developed for the simultaneous analysis of anions, monovalent cations and divalent cations. The detection limits for most ions are below 400-mu-g/l.
