摘要：

A new method to allow the simultaneous separation of anions and cations is proposed. It uses both the anion- and cation-exchange column connected in series, and uses two pumps with a flow-gradient capability. Two eluents delivered by these two pumps are merged in between the two columns. By varying me flow rates of two pumps and keeping the total flow-rate constant, retention times of both anions and cations can be controlled so that they are well separated. This new method was applied to a simultaneous separation of monovalent cations and anions. (C) 1999 Elsevier Science B.V. All rights reserved.
