What is ion exclusion chromatography? Free explanatory materials available.

What is ion exclusion chromatography? A thorough and easy-to-understand explanation of various methods such as ion exchange and ion pairing! Free foundational knowledge materials are currently available.

Ion exclusion chromatography uses ion exchange resin as the stationary phase, but unlike ion exchange chromatography, it utilizes the electrostatic repulsive forces between the ion exchange groups and the analytes. In the case of weak acids such as organic acids, the degree of dissociation in acidic solutions varies depending on the compound, leading to differences in charge strength. For analytes that have the same sign of charge as the ion exchange groups, the repulsive force received from the ion exchange groups varies according to the strength of that charge. This document provides a clear summary of the fundamentals of liquid chromatography (LC), detectors, and principles. It is a valuable resource for those learning HPLC for the first time, those who wish to review from the basics, and those looking for materials useful for in-house training.
