Comparison of monolithic approaches for enantioselective capillary electrochromatography involving cyclodextrins

The access to CD‐modified monoliths for enantiomeric separation by CEC can be divided into two main approaches. (i) Silica‐based monoliths, prepared by either a sol–gel process or by sintering of silica particles, are modified after fabrication by coating with a CD selector. Alternatively the fusion...

Summary:The access to CD‐modified monoliths for enantiomeric separation by CEC can be divided into two main approaches. (i) Silica‐based monoliths, prepared by either a sol–gel process or by sintering of silica particles, are modified after fabrication by coating with a CD selector. Alternatively the fusion of CD functionalized silica particle via gluing is feasible. (ii) Rigid or homogeneous organic polymer‐based monoliths, prepared by polymerization of organic monomers in the presence of a porogen, are modified with the CD selector either by copolymerization or by physical incorporation into the continuous bed.
