1. Essentially Lipids : Analytical methods for the characterization of lipid materials
Abstract : This thesis describes analytical methods for chromatographic characterizations of lipids in biological and technical systems.Lipids are a group of compounds with a central role in all known forms of life. In addition to the biological roles, lipids are also components in many products of our daily usage. READ MORE

2. On the reliability of methods for the speciation of mercury based on chromatographic separation coupled to atomic spectrometric detection
Abstract : This thesis deals with the reliability of methods for the speciation of mercury in environmental and biological samples. Problems with speciation methods that couple chromatography to atomic spectrometric detection and how to overcome the problems are discussed. READ MORE

3. Milk Folates: Characterisation and Availability
Abstract : With the ultimate goal to study milk folate bioavailability, a reverse-phase HPLC technique was developed and compared with a radioprotein binding assay. All methods showed similar ranges for folates in cow’s milk, with the variation attributed to seasonal variations and the use of different starter cultures. READ MORE

4. Reactions in the System Nitro-cellulose/ Diphenylamine with Special Reference to the Formation of a Stabilizing Product Bonded to Nitro-cellulose
Abstract : The methods HPLC, microcalorimetry and FTIR together with chemometry, provide good analytical tools to follow the degradation of nitro-cellulose.The degradation products formed from diphenylamine (DPA) during storage can be followed with HPLC. FTIR, together with chemometry, also gives the precision needed for safety control of propellants. READ MORE

5. Phylogeny, diversity and toxin production related to cyanobacterial symbioses
Abstract : Phylogeny and morphology were examined for the cyanobionts from the water fern Azolla and the cyanobacterial genus Nostoc originating from symbioses with different host plants (genera Gunnera, Cycas, Dioon, Encephalarthos, Macrozamia, and Anthoceros), the lichen genus Pannaria, and free-living Nostoc isolates from different habitats. Nostoc isolates of Pannaria formed a closely related group, but, in general, no monophyletic nature was attributed to the genus Nostoc, in contrast to the cyanobionts from Azolla which were contained in a unique monophyletic group.
