“…The quaternary ammonium anion-exchange latex nanoparticles (Dionex AS5A) with a diameter of 65 nm had been attached electrostatically to the inner wall of the capillary, and generated the reversal EOF for the separation of inorganic anions with o-CEC [22][23][24][25]. The separation was based on anion-exchange interaction.…”

This review summarizes most of the recent developments in the preparation and application of polar stationary phases for CEC covering the literature published since the year 2004. These polar stationary phases have been adopted for separation of analytes by the modes of packing column CEC, open-tubular CEC (o-CEC) and monolithic column CEC. Currently, development of o-CEC using biomolecules, such as protein and DNA, as the immobilized ligands is highlighted partly due to the simplicity of preparation. Furthermore, monolithic columns have been extended quickly, particularly inorganic materials-based monoliths, such as silica, zirconia, hafnium, etc., as an alternative to packed columns have been developed quickly.

“…Wall-coated capillaries for open-tubular IE-CEC can be prepared in a one-step process in which the surface silanols are modified with quaternary aminated latex particles [41,[149][150][151]. The latex particles bound electrostatically to the capillary wall introduce anion-exchange interactions with anionic analytes, the strength of which could be moderated by the type and concentration of the competing ion used in the BGE as well as the capillary diameter [149].…”

Capillary electrophoresis (CE) continues its invasion into the domain of inorganic analysis. This review summarizes the progress and significant developments of CE of inorganic ions over the first two years of the new century. As manifested by the substantial number of published articles, this field is still witnessing a growing activity of many separation scientists. To provide an in-depth treatment of fundamental and methodological aspects of inorganic ion analysis by CE, an extensive fraction of the relevant literature is covered whereas only most innovative application reports are briefly considered. Most of the recent advancements have focused on CE system modernization designed to improve a limited detection sensitivity, which still remains a major obstacle to overcome in order to ensure the method's wider practical acceptance. Attention is also given to how and in which directions the future research could be performed to implement CE in routine inorganic analysis.

“…These increased nearly two fold with 30% acetonitrile, for example, butyrophenone 101533 plates/ m. Usually higher efficiencies have been reported for less polar compounds, with 500 000 plates/m being achieved for PAHs [6,7], when significantly high concentrations of the organic modifier were used in the mobile phase. However, very low efficiencies (10 000 plates/meter) were reported for strongly interacting analytes on a 75 µm i.d OT column which were [13] attributed to the wider bore.…”

“…The sol-gel is usually bonded with a C 18 chain or any other organic moiety. Using these new column fabrication methods, capillaries with internal diameters of up to 75 µm have been formed for use in CEC [13 ]. It has been possible to use such relatively wider internal diameters because of the plug-like flow profile exhibited by capillary electrochromatography.…”
