11. Development of Enhanced Analytical Methodology in Pesticide Chemistry
Sammanfattning : The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties.

12. New Techniques for Sample Preparation in Analytical Chemistry : Microextraction in Packed Syringe (MEPS) and Methacrylate Based Monolithic Pipette Tips
Sammanfattning : Sample preparation is often a bottleneck in systems for chemical analysis. The aim of this work was to investigate and develop new techniques to address some of the shortcomings of current sample preparation methods. LÄS MER
13. Variance Reduction in Analytical Chemistry : New Numerical Methods in Chemometrics and Molecular Simulation
Sammanfattning : This thesis is based on five papers addressing variance reduction in different ways. The papers have in common that they all present new numerical methods. LÄS MER
14. New Techniques for Chiral Separations
Sammanfattning : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.

15. Electrochemical Aspects of Miniaturized Analytical Platforms
Sammanfattning : This thesis ties some electrochemical aspects of development and fabrication of an analytical system on a microchip together. These aspects develop through the fundamentals of amperometric detection in microsystems and microfabrication via the interaction of electrochemical detection and electrophoretic separation finally to the interfacing of a microsystem to the macro world.
