1. Development of the Lund AMS facility for the detection of Al-26 -- with applications in plant ecology
Sammanfattning : Accelerator mass spectrometry (AMS) is a highly sensitive technique to count atoms. The method has a high efficiency, which makes it possible to measure small samples in a relatively short time, usually less than an hour. During the work for this thesis, methods have been developed to detect Al-26 at the Lund AMS facility. LÄS MER
2. REXEBIS : an electron beam ion source for the REX-ISOLDE project
Sammanfattning : .... LÄS MER
3. Nanoparticles in capillary electrophoresis : what are the benefits?
Sammanfattning : Capillary electrophoresis is a technique that separate compounds based on charge and size. During the last two decades capillary electrophoresis (CE) and mass spectrometry (MS) has gained in interest, become more robust to use and able to separate neutral analytes. LÄS MER
4. Probing biomolecular fragmentation
Sammanfattning : This thesis deals with fragmentation of complex molecular ions, especially biomolecules, in gas phase collision experiments. The aim is to investigate the relations between energy deposition and fragmentation and to shed light on the mechanisms behind energy and charge transfer processes in collisions involving the building blocks of life.

5. 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
