   Sammanfattning : The advancement of mass spectrometry (MS) has been and continues to be a prominent analytical technique for highly accurate determination of analytes. The goal of this thesis was to develop new laser desorption ionization-mass spectrometric (LDI-MS) methods for analysis of polymer degradation products, additives and drugs. LÄS MER

3. 2. Hydrophilic Separation Materials for Liquid Chromatography

   Författare :Petrus Hemström; Knut Irgum; Peter Schoenmakers; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; HILIC; Hydrophilic; Stationary phase; Chemistry; Kemi;

   Sammanfattning : The main focus of this thesis is on hydrophilic interaction chromatography (HILIC) and the preparation of stationary phases for HILIC. The mechanism of HILIC is also discussed; a large part of the discussion has been adapted from a review written by me and professor Irgum for the Journal of Separation Science (ref 34). LÄS MER

4. 3. Fabrication of new silica nano structures and development of new concepts for MALDI-TOF mass spectrometry

   Författare :Andreas Woldegiorgis; Johan Roeraade; Peter J. Schoenmakers; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi;

   Sammanfattning : A technique to alter the morphology of the inner surface of fused silica capillaries has been developed. The internal surface area is enlarged by means of nano-wires of silica, which are grown from the capillary walls. LÄS MER
