Capillary electrochromatography using polyelectrolyte multilayer coatings

, 2005
This review covers recent progress in polyelectrolyte multilayer (PEM) coatings applied to-analytical separations using open-tubular capillary electrochromatography (OT-CEC). The simple preparation procedure involved in the PEM approach has provided some

Applications of capillary electrochromatography

, 1999
Applications performed by capillary electrochromatography (CEC) in all its modes, namely packed column CEC (packed-CEC), open tubular CEC (OT-CEC) and pressure-assisted CEC (pseudo-CEC), and published by June 1999 are reviewed. The review is divided into

Exploring the performance of cellulose tris-3,5-dichlorophenylcarbamate as a stationary phase for the chiral electro-chromatographic separation of azole antifungals

Journal of Chromatography Open
In this study, the enantiorecognition and separation performance of cellulose tris-3,5-dichlorophenylcarbamate (CDCPC) as the chiral selector for the enantioseparation of some chiral antifungal compounds was investigated.

Capillary electrochromatography with a silica column with a dynamically modified cationic surfactant

, 1999
A novel mode of capillary electrochromatography (CEC), called dynamically modified silica-capillary electrochromatography, is described in this paper. The column packed with bare silica was dynamically modified with long chain quaternary ammonium salt ...

Separation of basic and acidic compounds by capillary electrochromatography using monolithic silica capillary columns with zwitterionic stationary phase

, 2007
A novel monolithic silica column with zwitterionic stationary phase was prepared by in-situ covalent attachment of phenylalanine to a 3-glycidoxypropyltriethoxysilane-modified silica monolith.
