  1. 1. Superporous agarose a new material for chromatography

    Författare :Per-Erik Gustavsson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein separations; Chromatography; Superporous agarose; Continuous agarose beds; Intraparticle convection; Pore flow; Biochemistry; Metabolism; Biokemi; metabolism; Biotechnology; Bioteknik;

    Sammanfattning : Agarose, the most commonly employed chromatography base material in industrial purification processes for biomolecules – proteins, has almost ideal properties. The major disadvantage of the agarose support is its poor mechanical strength which excludes its use in high speed separations where small particles are needed in order to achieve improved chromatographic efficiency.

  3. 2. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

    Författare :Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. LÄS MER

  4. 3. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

    Författare :Mina Larsson; Jan Lindgren; Jean-Claude Lassègues; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; Chemistry; Kemi;

    Sammanfattning : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. LÄS MER

  5. 4. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

    Författare :Bernhard Walther; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

    Sammanfattning : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. LÄS MER
