Ion Exchange in Ion Chromatography
1989Of the many methods that have been applied to the chromatographic separation of ions, most employ ion exchangers. The purpose of this chapter is to describe some of the more important phenomena associated with the ion exchange process, to explain their physical causes, and to demonstrate how principles and theories of ion exchange relate to the ...

Ion exchangers consist of an insoluble framework (matrix) containing covalently bonded dissociable functional groups at accessible sites. These are either sulfonic acid groups or, less importantly, carboxyl groups in the case of cation exchangers, and tertiary amino or quaternary ammonium groups for anion exchangers.

Ion-Exchange Chromatography of Proteins
2003Ion-exchange chromatography is the most widely used technique in protein chromatography (1). This is because it is nearly always possible to develop successful ionexchange separations for proteins, and the materials required are relatively inexpensive.

Ion-exchange chromatography of nitrogen compounds
Journal of Chromatography A, 1974Abstract The review presents a systematic survey of ion-exchange methods for the analysis of nitrogen-containing compounds. The main interest is in cation-exchange separations of amines, nitrogen-containing bases and related compounds by elution with solutions of acids, buffers and salts and aqueous organic solvents and in highspeed chromatography of

Adsorption, Chromatography, Ion Exchange
2011Adsorption is the loading of solid surfaces with substances present in a surrounding fluid phase or, in other words, it is a surface effect between a solid and a fluid phase. Sometimes molecules of the fluid phase are not only fixed on the surface but can additionally enter the bulk of the nonporous solid phase according to a volume effect.

Ion-exchange chromatography of tissue nucleotides
Journal of Chromatography A, 1969Abstract A procedure has been devised for the isolation of soluble tissue nucleotides by ion-exchange chromatography on 1.0 × 90 cm columns of DEAE-Sephadex A-25, acetate form, using consecutive concave concentration gradients of the volatile salt triethylammonium acetate at pH 4.7.
