1. Aspects of Porous Graphitic Carbon as Packing Material in Capillary Liquid Chromatography
Sammanfattning : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

2. Analytical Approaches to Neurodegenerative Disease Protein Aggregation
Sammanfattning : .... LÄS MER
3. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC
Sammanfattning : This thesis concerns the development and validation of methods for characterization of multi-component preparative LC systems. Measurements of competitive adsorption isotherms are performed to gain detailed information about the interactions inside the chromatography column. LÄS MER
4. Development of Techniques and Methods for the Quantitative Analysis of Endogenous Substances by Microcolumn Liquid Chromatography Coupled to Mass Spectrometry
Sammanfattning : Liquid chromatography-mass spectrometry (LC-MS) is a powerful technique for the analysis of endogenous compounds. The introduction of electrospray ionization (ESI) as an interface between LC and MS has contributed strongly to a trend towards miniaturization of LC, due to the possibility to perform ESI at low flow rates.
