1. Sensitivity and selectivity studies in capillary electrophoresis
Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

2. New applications and developments of field-asymmetric ion mobility spectrometry - mass spectrometry (FAIMS-MS)
Sammanfattning : Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. LÄS MER
3. Molecularly Imprinted Matrices for Electrochromatography
Sammanfattning : This thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. LÄS MER
4. 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.

5. Introducing weak affinity chromatography to drug discovery with focus on fragment screening
Sammanfattning : Fragment-based drug discovery is an emerging process that has gained popularity in recent years. The process starts from small molecules called fragments. One major step in fragment-based drug discovery is fragment screening, which is a strategy to screen libraries of small molecules to find hits. LÄS MER
