  1. 1. Bioanalytical separation using capillary electrophoresis : Applications with microbubbles and proteins

    Författare :Leila Josefsson; Åsa Emmer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Background electrolyte; capillary electrophoresis; contrast agents; electroosmotic flow; ethylammonium nitrate; ionic liquids; microbubbles; particles; polyvinyl alcohol microbubbles; and separation; Kemi; Chemistry;

    Sammanfattning : In this thesis the possibilities of using capillary electrophoresis as a separation technique for analysis of proteins and microbubbles is presented.A complete analytical process consists of five necessary steps of which one is the actual analysis step. For this step a suitable analytical technique is needed. LÄS MER

  3. 2. Nanoparticles in capillary electrophoresis : what are the benefits?

    Författare :David Malmström; Jonas Bergquist; Charlotta Turner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    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. 3. Method development for affinity capillary electrophoresis of ß2-glycoprotein I and biological ligands

    Författare :Maria E. Bohlin; Lars G Blomberg; Niels H H Heegaard; Jan Leo Reubsaet; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capillary Electrophoresis; β2-glycoprotein I; acidic pretreatment; pH hysteresis effect; Affinity Capillary Electrophoresis; Kemi; Chemistry;

    Sammanfattning : The final goal of this study is to establish a microscale analysis method that allows solution phase characterization of interactions between β2-glycoprotein I (β2gpI) and some of its ligands. Human β2gpI is a phospholipid- and heparin-binding plasma glycoprotein. LÄS MER

  5. 4. Column Development in Capillary Electrophoresis and Electrochromatography for Bioanalytical Applications

    Författare :Nina Johannesson; Jonas Bergquist; Karin Markides; Abdul Malik; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Capillary electrophoresis CE ; Capillary electrochromatography CEC ; Mass spectrometry MS ; Bioanalysis; Sample pretreatment; Sol-gel; Analytisk kemi;

    Sammanfattning : Analysis of biological samples can be a difficult task. This thesis covers a broad aspect of the analytical areas of capillary electrophoresis (CE) and capillary electrochromatography (CEC) in combination with mass spectrometry (MS) that are of great importance for achieving fast, accurate and sensitive bioanalyses.

  7. 5. Zwitterionic Separation Materials for Liquid Chromatography and Capillary Electrophoresis : Synthesis, Characterization and Application for Inorganic Ion and Biomolecule Separations

    Författare :Wen Jiang; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Zwitterionic; stationary phase; separation; liquid chromatography; capillary electrophoresis; sulfobetaine; modification; covalently bonded; graft polymerization; ζ-potential; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Liquid Chromatography (LC) and Capillary Electrophoresis (CE) are modern analytical techniques that play very important roles in many areas of modern science such as life science, biotechnology, biomedicine, environmental studies, and development of pharmaceutics. Even though these two techniques have existed and been subjected to studies for several decades, the developments of new separation materials for them are still very important till now in order to meet the different new demands for improvement from other disciplines in science.
