1. Enantiomeric Separations using Chiral Counter-Ions
Sammanfattning : This thesis describes the use of chiral counter-ions for the enantiomeric separation of amines in non-aqueous capillary electrophoresis. The investigations have been concentrated on studies of the influence, of the chiral counter-ion, the solvent, the electrolyte and the analyte, on the enantioselective separation. LÄS MER
2. Enantioseparation of drugs and related compounds using chiral mobile phase additives
Sammanfattning : Neutral and anionic chiral mobile phase additives have been employed to separate enantiomers of drugs and related compounds using aqueous buffer solution and hydro-organic solvent mixtures as mobile phases.Ester derivatives of tartaric acid, e. g. LÄS MER
3. Chiral packed capillary chromatography using an in-column immobilized selector : With special emphasis on vancomycin
Sammanfattning : Packed fused silica capillary columns have been used for enantioseparation of drugs and related compounds. The technique to prepare the chiral stationary phase (CSP) involved a reductive amination of aldehyde functionalized silica with a chiral selector. The immobilization was performed in the packed column, thereby minimizing the use of selector. LÄS MER
4. Aspects of Optimisation of Separation of Drugs by Chemometrics
Sammanfattning : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. LÄS MER
