title: Miniaturization of capillary electrochromatography using an ultrashort capillary column.
abstract: The instrumentation for miniaturization of capillary electrochromatography was devised and an injection method for this apparatus was proposed. By using an ultra short capillary column (15 mm packed length, 36 mm total length, 75 microm inner diameter, packed with cation exchange supports), the separation of five biochemical compounds was performed within 1 min. The high separation efficiency of 9780 plates was achieved by using an ultrashort capillary column. The miniaturized instrumentation for capillary electrochromatography might be utilized as one of the possible methods in microfabricated analysis or in an alternative approach to it.
