1. Development of new and modified stationary phases in chromatography
Sammanfattning : .... LÄS MER
2. New tools for sample preparation and instrumental analysis of dioxins in environmental samples
Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), two groups of structurally related chlorinated aromatic hydrocarbons, are of high concern due to their global distribution and extreme toxicity. Since they occur at very low levels, their analysis is complex, challenging and hence there is a need for efficient, reliable and rapid alternative analytical methods. LÄS MER
3. Studies of some new chiral selectors and their use in enantioselective liquid chromatographic stationary phases
Sammanfattning : .... LÄS MER
4. Development and improvement of methods for characterization of HPLC stationary phases
Sammanfattning : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. LÄS MER
5. Hydrophilic Separation Materials for Liquid Chromatography
Sammanfattning : The main focus of this thesis is on hydrophilic interaction chromatography (HILIC) and the preparation of stationary phases for HILIC. The mechanism of HILIC is also discussed; a large part of the discussion has been adapted from a review written by me and professor Irgum for the Journal of Separation Science (ref 34). LÄS MER
