2. Development of LC-MS/MS Methods for the Analysis of Chiral and Achiral Pharmaceuticals and Metabolites in Aqueous Environmental Matrices
Abstract : This thesis describes the development of liquid chromatography tandem mass spectrometry (LC-MS/MS) methods for the trace analysis of active pharmaceutical ingredients (APIs) and their metabolites in aqueous environmental matrices. The research was focused on the development of chiral LC-MS/MS methods for the analysis of fluoxetine and metoprolol, as well as their chiral metabolites in environmental water samples. READ MORE

3. Selectivity in NMR and LC-MS Metabolomics : The Importance of Sample Preparation and Separation, and how to Measure Selectivity in LC-MS Metabolomics
Abstract : Until now, most metabolomics protocols have been optimized towards high sample throughput and high metabolite coverage, parameters considered to be highly important for identifying influenced biological pathways and to generate as many potential biomarkers as possible. From an analytical point of view this can be troubling, as neither sample throughput nor the number of signals relates to actual quality of the detected signals/metabolites. READ MORE

4. Analytical method development in liquid chromatography- mass spectrometry based metabolomics
Abstract : 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. READ MORE

5. Determination of the Environmental Fate of Drug Substances and the Matrix Effects of Complex Samples in SFC/ESI-MS
Abstract : Awareness of the potential problems caused by drug compounds in the environment has increased over the last decade, both among researchers and with the public. This thesis describes the development of analytical methods and their application to wetlands constructed for purification of wastewater from e.g. drug compounds. READ MORE
