3. 22. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

   Författare :Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
   Nyckelord :acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

   Sammanfattning : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. LÄS MER

4. 23. Analysis of lignin monomers and oligomers in technical lignins using chromatography and mass spectrometry

   Författare :Jens Prothmann; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lignin; Mass spectromery; Chromatography;

   Sammanfattning : Lignin is the most abundant aromatic biopolymer on earth and has the potential to play an important role in the transition from an oil-based refinery to a biorefinery-based industry. The isolation of lignin from the biomass can be achieved by several different technical processes and isolated lignins are referred to as technical lignins in literature. LÄS MER

5. 24. Retention time predictions in Gas Chromatography

   Författare :Yasar Thewalim; Anders Colmsjö; Torgny Fornstedt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; computer simulation; two-parameter model; retention time prediction; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : In gas chromatography, analytes are separated by differences in their partition between a mobile phase and a stationary phase. Temperature-program, column dimensions, stationary and mobile phases, and flow rate are all parameters that can affect the quality of the separation in gas chromatography. LÄS MER

7. 25. Multimodal Interaction Chromatography for the Investigation and Separation of Proteins

   Författare :Kristian Kallberg; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrophobic interaction chromatography; Multimodal chromatography; Glycosylation; Antibody; Hemoglobin; Protein purification.;

   Sammanfattning : Minor structural changes on the surface of proteins can have tremendous impact on their biological properties. When producing therapeutic proteins it is therefore important to verify that the generated protein is the desired one. LÄS MER
