Disaccharide Composition in Glycosaminoglycans/Proteoglycans Analyzed by Capillary Zone Electrophoresis
During the past decade, the use of fully automated equipment for capillary electrophoresis (CE) has made this a routine method for the study of soluble analytes. The separation of such compounds in capillaries (20–200 µm id) and in strong electric fields (around 50 kV/m) seems to be exceptionally efficient for separating both large and small molecules. The most common type of CE is capillary zone electrophoresis (CZE), which is done with the separation buffer free in an otherwise empty capillary. These separations, in principle, share some features not only with gel electrophoresis but also with high-performance liquid chromatography (HPLC), and they provide a unique combination of both analytical techniques. CZE is therefore an alternative to HPLC and it is sometimes advantageous because there are no problems related to laminar flow and other wall effects.
