1. Fundamental Investigations of Adsorption in SFC
Sammanfattning : In supercritical fluid chromatography (SFC), the eluent is composed by carbon dioxide, often with additional components, in a condition between gas and liquid. This thesis aims to reach a deeper understanding of SFC by revealing the function of the additional eluent components through systematic adsorption studies. LÄS MER
2. Fundamental Investigations of Supercritical Fluid Chromatography
Sammanfattning : This thesis aims at a deeper understanding of Supercritical FluidChromatography (SFC). Although preparative SFC has started to replace Liquid Chromatography (LC) in the pharmaceutical industry - because of its advantages in speed and its less environmental impact - fundamental understanding is still lacking. LÄS MER
3. Analytical Supercritical Fluid Extraction of Lipid Containing Samples
Sammanfattning : Traditionally, sample work-up has been associated with different kinds of liquid extraction techniques involving a large consumption of hazardous solvents. There are today regulations that aims at replacement of dangerous chemicals which has created a need for new extraction techniques. LÄS MER
4. Innovatie Core Concepts for Future Aero Engines
Sammanfattning : .... LÄS MER
5. Determination of the Environmental Fate of Drug Substances and the Matrix Effects of Complex Samples in SFC/ESI-MS
Sammanfattning : Awareness of the potential problems caused by drug compounds in the environment has increased over the last decade, both among researchers and with the public. This thesis describes the development of analytical methods and their application to wetlands constructed for purification of wastewater from e.g. drug compounds. LÄS MER
