ABSTRACT:
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 having an interconnected polymeric coating. The interconnected polymeric coating includes a hydrophobic hydrocarbon polymeric functionality covalently bound to the interior surface and polyvinylalcohol interconnected with the hydrophobic polymeric functionality. Exemplary columns are prepared by causing a Si-OH reactive compound, having a hydrophobic polymeric functionality, to react with Si-OH functionalities on the interior surface of capillary columns. Then causing vinyl acetate to polymerize in contact with the hydrophobic polymeric functionality and hydrolyzing the resulting polyvinylacetate forms a coating of interconnecting hydrophilic and hydrophobic polymers.
