Analytica Chimica Acta, 1967
Abstract A review is given of variables which affect the separation factors in ion-exchange chromatography. In favorable cases the influence of complex formation, pH, and eluant concentration can be predicted by simple calculations, whereas the interaction forces inside the resin phase are still largely unexplored.

Ion Exchange in Paper Chromatography
Nature, 1953IT has been shown by Schute that several mixtures of alkaloids can be separated by chromatography on paper using aqueous ammonia1. Because the chromatograms have the characteristics of a partition chromatogram, it is probable that the above separation is due to partition between an aqueous imbibition phase and an aqueous mobile phase.

Ion-Exchange Chromatography in Alcohol
Nature, 1955IN the technique of ion-exchange chromatography, the order in which compounds are eluted from a column depends basically upon differences in their ionization constants; but other factors modify and in many instances reverse the expected order1. This is illustrated in Fig.

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 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.
