Abstract
An on-column derivatization scheme where a liquid or solid labeling reagent is provided in a capillary to react chemically with a sample in order to label the sample. Electrophoretic separation may be carried out immediately thereafter to simplify the derivatization, separation and detection process. By localizing the labeling process to a small area within the capillary, fast kinetics and high reaction yield are achieved.
