PPT-Ch rom ato gra phy 1 Ion Exchange Chromatography

Definition Ionexchange chromatography or ion chromatography is a process that allows the separation of ions and polar molecules based on the charge properties of the molecules 1975 by Small Stevens and Baumann.

Chromatography is a technique of separation of different dissolved constituents of a mixture by absorbing them over an appropriate adsorbent material .It is a versatile method of separating different kinds of chemical mixtures .. Principle and Definition. Principle. The principle of chromatographic separation is very simple. The process is achieved by . distributing the substances. to be separated between a . mobile phase. and a . Jane King. Chief Information Officer. 09 September 2015. UNCLASSIFIED - ATO . SwD.
