11. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry
Sammanfattning : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. LÄS MER
12. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications
Sammanfattning : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

14. Chiral Recognition by Means of Mass Spectrometry
Sammanfattning : This thesis is based on experimental studies of chiral ions in gas-phase. Electrospray ion source platform (Stockholm University) and commercially available Quadrupole Time-of-Flight mass spectrometer have been used in our studies. LÄS MER
15. Secondary and Higher Order Structural Characterization of Peptides and Proteins by Mass Spectrometry
Sammanfattning : The work in this thesis has demonstrated the advantages and limitations of using MS based technologies in protein and peptide structural studies. Tandem MS, specifically electron capture dissociation (ECD) have shown the ability to provide structural insights in molecules containing the slightest of all modifications (D-AA substitution).
