6. Liquid Chromatography Coupled to Mass Spectrometry : Implementation of Chemometric Optimization and Selected Applications
Abstract : Liquid chromatography (LC) coupled to mass spectrometry (MS) offers highly selective and sensitive analysis of a wide variety of compounds. However, the use of hyphenated experimental set-ups implies that many parameters may have an effect on the studied response. READ MORE

7. GC-MS based metabolomics – Development of a next generation GC-MS method and its application to nutrition and biomarker research
Abstract : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. READ MORE

8. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure
Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE

9. Identification and Characterization of Peptides and Proteins using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
Abstract : Mass spectrometry has in recent years been established as the standard method for protein identification and characterization in proteomics with excellent intrinsic sensitivity and specificity. Fourier transform ion cyclotron resonance is the mass spectrometric technique that provides the highest resolving power and mass accuracy, increasing the amount of information that can be obtained from complex samples.

10. Development of Enhanced Analytical Methodology for Lipid Analysis from Sampling to Detection : A Targeted Lipidomics Approach
Abstract : This thesis covers a wide range of analytical method development for lipid analysis in complex biological samples; from sample preparation using pressurized fluid extraction (PFE) and separation with reversed phase capillary liquid chromatography (RP-LC) to detection by electrospray ionization mass spectrometry (ESI/MS) and tandem MS.The requirements for fast, reliable and selective extraction methods with minimal usage of solvents have accelerated the development of new extraction techniques.
