Chiral separation by chromatographic and electromigration techniques. A Review
Gerald Gübitz,Martin G. Schmid +1 more
TL;DR: This review gives a survey of different chiral separation principles and their use in high‐performance liquid chromatography (HPLC), gas chromatography, supercritical fluid Chromatography (SFC), thin‐layer chromatography(TLC), capillary electrophoresis (CE) and capillary electrochromatography (CEC) highlighting new developments and innovative techniques.
Journal ArticleDOI
Development and application of polymeric monolithic stationary phases for capillary electrochromatography.
TL;DR: This review summarizes results excerpted from numerous papers concerning this rapidly growing area with a focus on monoliths prepared from synthetic polymers, which are now a well-established stationary phase format in the field of capillary electrochromatography.
Journal ArticleDOI
Recent progress in chiral separation principles in capillary electrophoresis
Gerald Gübitz,Martin G. Schmid +1 more
TL;DR: This review summarizes recent developments in the field of chiral separations by electromigration techniques including capillary zone electrophoresis (CZE), capillary gel electrophysiology (CGE), isotachophoresis, electrokinetic chromatography (EKC), and capillary electrochromatography (CEC).
Journal ArticleDOI
Chiral Monolithic Columns for Enantioselective Capillary Electrochromatography Prepared by Copolymerization of a Monomer with Quinidine Functionality. 1. Optimization of Polymerization Conditions, Porous Properties, and Chemistry of the Stationary Phase
Michael Lämmerhofer,Eric C. Peters,Cong Yu,and Frantisek Svec,Jean M. J. Fréchet,Wolfgang Lindner +5 more
TL;DR: The ability to control pore size independently of the polymerization mixture composition enables the preparation of monoliths with varying percentages of the chiral monomer and cross-linker, as well as the optimization of their separation properties.
Journal ArticleDOI
Preparation of Perphenylcarbamoylated β-Cyclodextrin-silica Hybrid Monolithic Column with “One-Pot” Approach for Enantioseparation by Capillary Liquid Chromatography
TL;DR: The limitation and difficulty of the use of water insoluble organic monomers in the previously reported " one-pot" method was circumvented and various β-CD derivatives as well as other hydrophobic monomers could thus be used to prepare organic-silica hybrid monolithic columns with the "one- Pot" process.

Journal ArticleDOI
Molecular Imprinting in Cross‐Linked Materials with the Aid of Molecular Templates— A Way towards Artificial Antibodies
TL;DR: In this article, the authors present a method analogous to a mechanism of antibody formation proposed earlier, by which in the presence of interacting monomers a cross-linked polymer is formed around a molecule that acts as a template.
Journal ArticleDOI
Molded Rigid Polymer Monoliths as Separation Media for Capillary Electrochromatography. 1. Fine Control of Porous Properties and Surface Chemistry
TL;DR: Measurements on monoliths with increasing levels of AMPS in which the pore size remains fixed show no deterioration in efficiency while maintaining the same increase in flow velocity, thus producing a significant reduction in separation time.
Journal ArticleDOI
Macroporous Polyacrylamide/Poly(ethylene glycol) Matrixes as Stationary Phases in Capillary Electrochromatography
Anders Palm and,Milos V. Novotny +1 more
TL;DR: In this paper, a one-step method is described for in situ preparation of macroporous polymeric matrixes to be used as stationary phases for capillary electrochromatography.
Journal ArticleDOI
Molded rigid polymer monoliths as separation media for capillary electrochromatography. 2. Effect of chromatographic conditions on the separation.
TL;DR: The electroosmotically driven size exclusion chromatography of polystyrene standards with molecular weights up to 10(6) has been demonstrated for the first time and found to be proportional to the strength of the electric field and both the pH and the composition of the mobile phase.
Journal ArticleDOI
Fritless packed columns for capillary electrochromatography: separation of uncharged compounds on hydrophobic hydrogels.
TL;DR: A novel column is described that does not require frits to keep packing material within a capillary, and is an alternative to packed capillary columns which have been used previously in CEC.
