An investigation into the use of B-cyclodextrins as additives to effect enantiomeric separation by reversed phase HPLC.
… methods, both analytical and preparative for the separation of enantiomers. The present range of analytical methods used for chromatographic separation and quantification of enantiomers is discussed. The ability of B-cyclodextrin (CD) as mobile phase additive in reversed phase HPLC to bring about …

Design, synthesis, and exploration of a chimeric antioxidant and new crosslinkers for molecular imprinting
… (MIP) composition related to performance as separation media is examined. Crosslinkers account for the bulk of MIP formulations made through traditional imprinting (80-90%) and is even greater when the One Monomer Molecularly Imprinted Polymer (OMNiMIP) approach is utilized (100%.) It is not …

Chromatographic studies and analytical methods development for selected tetraazamacrocycles and their copper(II) complexes
… and therapeutic agents. The development of separation conditions is important in evaluating their purity as well as assessment of their physical properties including conditional formation constants, acid dissociation constants and lipophilicity, which can have a major bearing on the in vivo …

Enantiomeric separations by HPLC:temperature, mobile phase, flow rate and retention mechanism studies
… flow rate, and stationary phase upon the enantiomeric separation of several racemic mixtures are investigated. The changes in capacity factor (k'), selectivity (α), and efficiency (N) and enantiomeric resolution (R), are explored. Resolution is then shown to be controlled by the specific …

Super-aptamer bio-imprinted hydrogels : an investigation into the optimization and characterization of cross-linked polymeric materials displaying macromolecular amplified responses
… moleculary imprinted polymer material capable of enantiomeric separation. Its further characterization was explored here concerning its ability to be used as a binding receptor in concert with its role in reducing polymer matrix non-selective binding. The deconvolution of this duality could lead …
