Recent advances have stimulated interest concerning the development of microcolumn liquid-phase separation methods, including capillary liquid chromatography in various forms, and capillary zone electrophoresis. It has become increasingly evident that microcolumn techniques, especially those employing capillary columns (<100 μm i.d.), offer several advantages over conventional liquid-phase techniques (1). One significant advantage of microcolumn methods is the suitability for determining solutes from extremely small-volume samples. This prospect is exceedingly important for many biological analyses.
