Analytical separations using packed and open-tubular capillary electrochromatography
… is to develop packed and open-tubular capillary electrochromatographic methods for improved achiral and chiral separations of various classes of analytes. The first part of this research involves the separation of seven benzodiazepines by the use of the packed mode of capillary …

Investigations of Chiral Recognition Processes
… CSP in a promising new analytical technique, capillary electrochromatography (CEC), was also investigated. The chiral selector was bonded to silica support (3 mum, 100 A pore size), packed into capillaries (100 mum i.d.), and evaluated under different conditions to determine optimal …

The modeling and analysis of the electroosmotic flow, diffusion, electrophoretic migration, and adsorption mechanisms of charged and uncharged adsorbates in capillary electrochromatography systems employing charged adsorbent particles - comparisons between theory and experiments
… in charged chromatographic media employed in capillary electrochromatography (CEC) and ion exchange systems are modeled, studied, and analyzed. The modelling of these mechanisms has put the analysis of the dynamic behavior of CEC systems to now be based on fundamental scientific understanding …

Applications of Brush-Type Chiral Stationary Phases in New Chromatographic Techniques
… in chiral discrimination are investigated. Capillary electrochromatography, a hybrid of capillary electrophoresis and high-performance liquid chromatography has been used to study the enantioseparations of hydantoins and thiohydantoins. Thiohydantoins are a class of compounds that typically …

ELECTROKINETIC SEPARATIONS ON MICROFLUIDIC DEVICES FOR N-GLYCAN PROFILING
… A direct comparison between microchip and capillary electrophoresis demonstrated the separation performance on microchips was as good as or better than on capillaries. Statistical analysis of the glycan profiles derived from blood serum samples revealed differences between healthy …

Development and applications of electrically driven separation methods.
Capillary Electrochromatography (CEC) is one of the newest separation techniques. It is a hybrid technique of high performance liquid chromatography (HPLC) and capillary zone electrophoresis (CZE). It combines the simplest capillary electrophoresis mode where separations are based on the …

Fabrication of surface amine gradients by controlled-rate infusion for chromatographic applications
… as these would be useful in open-tubular capillary electrochromatography for separation of complex mixtures and also to study the retention behavior of various components. This was achieved by carefully infusing micro-volumes of APTEOS solution into the activated silica capillaries. To …
