   Sammanfattning : Vaccines that are safe, efficacious, and can be rapidly developed are needed to prevent and to react to emerging global infectious disease threats such as influenza, Polio, and Coronavirus diseases. Fast and reliable analytical methods are required without delay to support vaccine process and product development, characterization, and quality control testing. LÄS MER

3. 12. Development of Sheathless Electrospray Mass Spectrometry and Investigations of Associated Electrochemical Processes – A Fairy Tale

   Författare :Stefan Nilsson; Karin Markides; Leif Nyholm; Jonas Bergquist; Per Andrén; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; electrospray; sheathless; mass spectrometry; capillary electrophoresis; electrochemistry; chromatography; interface; fairy dust; gold; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : In microscale separations, such as capillary electrophoresis and -liquid chromatography, the liquid flow rates are in the order of nanoliters per second. If such flow rates are to be interfaced with a mass spectrometer (MS) using electrospray (ES) ionization, without loss of separation efficiency, each fraction of the analyte zone must remain undisturbed by the high voltage contact necessary for ES.

5. 14. Characterisation of kraft pulps by size-exclusion chromatography and kraft lignin samples by capillary zone electrophoresis

   Författare :Elisabeth Sjöholm; KTH; []
   Nyckelord :;

   Sammanfattning : In the present thesis two analytical methods forcharacterisation of underivatised pulp and lignin samplesobtained from kraft pulping of hardwood and softwood areevaluated. The first method is the use of lithiumchloride/N,N-dimethylacetamide (LiCl/DMAc) for dissolution andsize-exclusion chromatography (SEC) of pulps. LÄS MER

7. 15. Capillary electrophoresis and multivariate calibration in the analysis of natural waters

   Författare :Johan Dahlén; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : The aim of this work was to explore the applicability of capillary zone electrophoresis (CZE) and multivariate partial least squares (PLS) regression in the analysis of organic compounds and inorganic ions in natural waters. A new CZE application was developed to analyze low molecular weight (LMW) organic acids. LÄS MER
