Abstract

[2-(Methacryloyl)oxyethyl]trimethylammonium chloride was successfully polymd. by surface-initiated atom transfer radical polymn. method on the inner surface of fused-silica capillaries resulting in a covalently bound poly([2-(methacryloyl)oxyethyl]trimethylammonium chloride) coating. The coated capillaries provided in capillary electrophoresis an excellent run-to-run repeatability, capillary-to-capillary and day-to-day reproducibility. The capillaries worked reliably over 1 mo with EOF repeatability
