1. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS
Sammanfattning : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

2. Analysis of proteins related toautoimmune and inflammatorydiseases with focus on newenrichment methodologies and MALDI-TOF MS
Sammanfattning : Proteins have been widely studied in biological sample analysis due to the association with diseases. In the present project, method and technique development was carried out on the analysis of two proteins, immunoglobulin G (IgG) and osteopontin (OPN). LÄS MER
3. Sampling and Selective Detection of Peptides and Proteins Emphazing Microdialysis,Bio-recognition Assays and MALDI-TOF MS
Sammanfattning : The use of microdialysis sampling and flow immunochemical detection as well as MALDI-TOF MS for peptide and protein analysis is described. Sampling of peptides and smaller proteins was investigated with different membranes. LÄS MER
4. Improved mass accuracy in MALDI-TOF-MS analysis
Sammanfattning : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. LÄS MER
5. New Tools for Analysis of Wood and Pulp Components - Application of MALDI-TOF Mass Spectroscopy and Capillary Zone Electrophoresis
Sammanfattning : In the present thesis, capillary zone electrophoresis (CZE),matrix-assisted laser desorption/ionization time-of-flight massspectroscopy (MALDI-MS) and size-exclusion chromatography incombination with off-line MALDI-MS (SEC/MALDI-MS) have beenapplied successfully to the analysis of wood and pulpcomponents.The carbohydrate compositions of pulp and holocellulosesamples, as well as of isolated hemicellulose preparations,were determined employing enzymatic hydrolysis and subsequentanalysis of the saccharides released by CZE.
