21. Enantiomeric separations by capillary electrophoresis in pharmaceutical analysis
Sammanfattning : The chiral capillary electrophoresis mechanism is studied by evaluating the enantiomeric separations of a series of local anaesthetic analogues, the sixteen different optical isomers of a tetrapeptide and a series of glycyl, alanyl and leucyl dipeptides. The usefulness of mobility difference plots is appraised and important method parameters, such as the selection of the chiral selector, the chiral selector concentration, the chiral selector purity, the pH and the composition of the electrophoresis solution, are identified and discussed, bearing method robustness in mind.

22. Functional regulation of the dopaminergic system in vivo : Experimental and clinical studies with positron emission tomography
Sammanfattning : Positron emission tomography (PET) is a non-invasive imaging technique used to quantitate the kinetics of a radiotracer in such physiological processes as receptor binding and enzyme activity. Radiolabelled L-DOPA has previously been used as a tracer for the dopaminergic system. LÄS MER
23. Direct injection of plasma samples into restricted-access media precolumns for drug analysis in column-switching systems
Sammanfattning : This thesis focuses on the theoretical and practical aspects of using column-switching systems for direct injection of plasma samples to assay drugs at ng/ml levels. The systems utilized a restricted-access media (RAM) precolumn for the sample clean-up and trace enrichment. LÄS MER
24. Analytical method development in liquid chromatography- mass spectrometry based metabolomics
Sammanfattning : Metabolomics is the analytical field which aims at analyzing all small molecules, metabolites, in a biological system simultaneously. Currently no analytical methods are able to capture the entire metabolome, therefore, the analytical methods are often developed to be as general as possible. LÄS MER
25. Investigation of degradation of toxic substances in fungal cultures by mass spectrometric techniques
Sammanfattning : Micropollutants in water are biological or chemical contaminants that are present in ground and surface waters in trace quantities. They are a result of human activity and include pharmaceutically active compounds (PhACs) and endocrine disrupting compounds (EDCs). LÄS MER
