Abstract
A series of N-D-gluco-N-methylalkanamide (MEGA) surfactants was evaluated in micellar electrokinetic capillary chromatography (MECC) of neutral and charged species. The nonionic MEGA surfactants are readily converted in situ to anionic borate complexes through the association between their polyhydroxy head groups and borate ions at alkaline pH. The MEGA-borate complex surfactants yielded micelles with adjustable surface charge density, and consequently, the magnitude of the retention window was readily altered by the pH and the concentration of borate in the running electrolyte
