ABSTRACT:
The present invention provides for the convenient preparation, purification, use and re-use of capillary electrochromatography columns that employ polymer gel materials as the separation media. The problems associated with employing crosslinked polymer gels is overcome through the use of physically entangled polymer gels, which comprise, as polymerized units: 1) 5% to 80% by weight of an ionizable monomer; 2) 0.1% to 50% by weight of a monomer containing a retentive ligand; and 3) 10% to 80% by weight of a nonionic monomer.
