A method for the analysis of oligosaccharides was described using capillary elec-trophoresis. The oligosaccharides were derivatized with naphthylamine, and separated by high-performance capillary electrophoresis in the borax buffer solution as carrier. A comparison between capillary zone electrophoresis (CZE) and micellar electrokinetic capillary chomatography (MECC) of oligosaccharides-ot-naphthylamine was made. The results indicate that the separation of oligosaccharides-a-naphthylamines is better by MECC...
