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
## Abstract Capillary electrochromatography (CEC) with a novel stationary phase, 3‐(4‐sulfo‐1,8‐naphthalimido)propyl‐modified silyl silica gel (SNAIP), proved useful for the separation of nucleosides and nucleic acid bases. The application scope of SNAIP, which is a relatively polar reversed‐phase
## Abstract The potential of 3‐(4‐sulfo‐1,8‐naphthalimido)propyl‐modified silyl silica gel (SNAIP) as a mixed‐mode stationary phase for capillary electrochromatography (CEC) was investigated for the separation of charged analytes, taking four amino acids (tyrosine, phenylalanine, tryptophan, histid
