Apparatus for chromatographic ion analysis and method of chromatographic ion analysis.

摘要

Apparatus for chromatographic analysis comprising an eluent reservoir, a chromatographic separating means in communication with said reservoir for receiving eluent containing an electrolyte in solution therefrom, said separating means including a separating medium useful for separating ionic species of a sample eluted therethrough, a stripper device communicating with said separating means for treating effluent eluted therefrom said stripper device comprising a strong acid or strong base ion-exchange membrane for partitioning a regenerant from the effluent of the separating means, said membrane being preferentially permeable to ions of the same charge as exchangeable ions of said membrane, the exchangeable ions of said membrane provided by the regenerant being of the form to convert the electrolyte of the eluent to a weakly ionized form, and a detector means for detecting resolved ionic species communicating with the stripper device for receiving the treated effluent therefrom and method of chromatographic ion analysis.
