description Coated capillary electrophoresis columns and methods for their use in electrophoretic separations are disclosed. The coated capillary columns include a length of tubing having an interior surface coated with at least one crosslinked organic multi-valent ionic compound capable of ionic interaction with charged chemical functionalities on the tubing interior surface. Exemplary columns are prepared by crosslinking a multi-functional amine compound with a diexpoxide, alkylating the crosslinked multi-functional amine compound to form a crosslinked quaternary ammonium compound, and then contacting the interior surface of capillary tubing with the crosslinked quaternary ammonium compound.
