ABSTRACT:
Coated capillary tubes useful for performing free electrophoretic separation techniques are prepared by reacting the interior wall of the tube with a bifunctional compound having a first functional group capable of covalently attaching to the wall and a second functional group capable of being polymerized. After such covalent attachment, free monomer is reacted with the second functional group, resulting in the formation of a monomolecular polymeric layer covalently attached to the interior wall of the capillary tube. This polymeric layer inhibits electroendosmosis and adsorption of the substances to be separated onto the interior of the tube, providing for improved separation.
