2. New Materials and Improved Ambient Techniques in Mass Spectrometry
Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER
3. Development and application of alternative methods for profiling proteins N-glycosylation
Sammanfattning : Glycosylation is a post-translational modification (PTM) that exerts profound structural and functional effects on the modified protein. Glycan synthesis and conjugation to proteins are regulated by a myriad of factors, both genetic and environmental, and are also influenced by external stressors. LÄS MER
4. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap
Sammanfattning : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. LÄS MER
