1. Metabolic Studies with Liquid Separation Coupled to Mass Spectrometry
Sammanfattning : Metabolism is the sum of all chemical processes with the purpose to maintain life, as well as enable reproduction, in a living organism. Through the study of metabolism, increased understanding of pharmacological mechanisms and diseases can be achieved. LÄS MER
2. Cerebrum Illuminans : Mass Spectrometric Analysis of Protein and Peptide Dynamics in Neurological Diseases
Sammanfattning : The human brain (lat. cerebrum) is the most complex and heterogeneous organ in the human body. It is involved in a great number of body functions like movement, touch sensing, vision, hearing, smelling, hormone regulation and many more. In no other organ, the molecular communication mechanisms between different cells are so poorly understood. LÄS MER
3. New Tools for Trapping and Separation in Gas Chromatography and Dielectrophoresis : Improved Performance by Aid of Computer Simulation
Sammanfattning : Computer simulations can be useful aids for both developing new analytical methods and enhancing the performance of existing techniques. This thesis is based on studies in which computer simulations were key elements in the development of several new tools for use in gas chromatography and dielectrophoresis. LÄS MER
4. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices
Sammanfattning : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. LÄS MER
5. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements
Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER
