“…Mobile phases were prepared by packed columns with dynamically modified by cetylmixing appropriate volume of phosphate buffer, trimethylammonium bromide as the reversed-phase acetonitrile and ultra-pure water. Before running, the stationary phase in CEC were developed [20,21]. mobile phase was degassed in an ultrasonic bath for To date, only a few CEC separations have been 30 min.…”

“…Comparing triethanolamine (TEOA) and triethylamine (TEA) as additives, they found TEOA had the more desirable effects on separation to improve peak symmetry, while a high EOF was still maintained for its lesser degree of masking for silanol groups on the inner surface. Ye et al [27] also regulated the retention properties of basic compounds on a bare silica column by dynamically modifying it with cationic surfactant.…”

This review article summarizes the variety of polar stationary phases that have been employed for capillary electrochromatographic separations. Compared with reversedphase stationary phases, the polar alternatives provide a completely different retention selectivity towards polar and charged analytes. Different types of polar stationary phases are reviewed, including the possible retention mechanisms. Electrochromatographic separations of polar solutes, peptides, and basic pharmaceuticals on polar stationary phases are presented.

“…A tentacular anion-exchanger for protein separations in the PC-CEC mode was also developed by the same group [16]. Basic peptides were separated on a bare-silica packed column dynamically modi®ed with cetyltrimethylammonium bromide, which was added into the mobile phase [17].Monolithic column based capillary electrochromatography of peptides and proteins CEC separations on monoliths are an attractive technology, mainly because it is easy to prepare the stationary phases, and the retaining frits are no longer necessary [18,19]. Separation of proteins and peptides in monolith CEC was mostly performed in the`counterdirectional mode'.…”
