1. Monolithic separation media synthesized in capillaries and their applications for molecularly imprinted networks
Sammanfattning : The thesis describes the synthesis of chromatographic media using several different approaches, their characterizations and applications in liquid chromatography. The steps to achieve a separation column for a specific analyte are presented. The main focus of the study was the design of novel molecularly imprinted polymers. LÄS MER
2. Surface Modified Capillaries in Capillary Electrophoresis Coupled to Mass Spectrometry : Method Development and Exploration of the Potential of Capillary Electrophoresis as a Proteomic Tool
Sammanfattning : The increased knowledge about the complexity of the physiological processes increases the demand on the analytical techniques employed to explore them. A comprehensive analysis of the entire sample content is today the most common approach to investigate the molecular interplay behind a physiological deviation. LÄS MER
3. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances
Sammanfattning : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. LÄS MER
4. Fabrication of new silica nano structures and development of new concepts for MALDI-TOF mass spectrometry
Sammanfattning : A technique to alter the morphology of the inner surface of fused silica capillaries has been developed. The internal surface area is enlarged by means of nano-wires of silica, which are grown from the capillary walls. LÄS MER
5. Development of techniques and methods for drug analysis by packed capillary liquid chromatography with octadecylbonded silica and porous graphitic carbon columns
Sammanfattning : Packed capillary liquid chromatography in combination with ultraviolet and mass spectrometric (MS) detection was explored as an analytical tool for drug analysis. The focus was put on column and sample preparation techniques as well as on fundamental aspects and development of chromatographic separations. LÄS MER
