Abstract
A permselective ion-exchange membrane, preferably comprising hollow fiber(s) immersed within a regenerant, is used to selectively neutralize or suppress the conductivity of electrolyte in a stream of eluent also containing chromatographically separated ions. The invention particularly specifies a chromatographic separating column useful with an electrolyte eluent solution to separate ionic species by elution chromatography, wherein the effluent of the separator column is treated by the described membrane to suppress the conductivity of the electrolyte but not that of the separated ions.
