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. The ODSS stationary phase is composed of a hydrophilic, negat

An increase in both retention and enantioselectivity for some beta-blocking agents was observed when exchanging potassium to sodium ion in the buffer used as mobile phase. A large effect of ionic strength on retention was observed, while the enantioselectivity was constant.
