Abstract

An electrophoretic or chromatographic separation capillary containing a fluid defines a bore therein through which a sample travels and separates into components. The tube has a side wall defining a through hole therein which is surrounded by a medium including a substance. The substance is introduced into the capillary through the hole by means of gravity, pressure or electroosmosis. The substance introduced may be used to label sample components to enhance detection, or to enhance separation of sample components.
