## Use of vancomycin silica stationary phase in packed capillary electrochromatography: III. Enantiomeric separation of basic compounds with the polar organic mobile phase The separation of basic compounds into their enantiomers was achieved using capillary electrochromatography in 50 or 75 mm inn
## Abstract The discrimination ability of three celluloseโbased chiral stationary phases (CSPs) was evaluated towards the enantiomers of basic drugs, using ACN as the main solvent in polar organic mobile phases. The study was focused on CSPs containing cellulose tris(3โchloroโ4โmethylphenylcarbamat
An octadecyl-sulfonated silica (ODSS) stationary phase specially designed for performing capillary electrochromatography (CEC) at relatively strong electroosmotic flow (EOF) proved useful for the separations of some nucleosides and bases.
