11. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC
Sammanfattning : This thesis concerns the development and validation of methods for characterization of multi-component preparative LC systems. Measurements of competitive adsorption isotherms are performed to gain detailed information about the interactions inside the chromatography column. LÄS MER
12. Tartaric acid derivatives as chiral selectors in liquid chromatography
Sammanfattning : .... LÄS MER
13. Direct separation of enantiomers using chiral ion-pair chromatography
Sammanfattning : .... LÄS MER
14. 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
15. A study of the stereochemistry and electronic transitions of cyclic and acyclic thioamides by crystallography, spectroscopy and computational methods
Sammanfattning : Analysis of conformations and electron transitions of 3-(alkyl or aralkyl)-5-(methyl or phenyl)rhodanines with analogues and N,N'-bis[(S)-1-phenylethyl]-thiourea have been performed by X-ray crystallography, 1H NMR, molecular mechanics, ultraviolet spectroscopy and for the chiral rhodanines, enantiomer chromatography and circular dichroism spectroscopy. The magnitude of rotational barriers has been determined. LÄS MER
