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

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

   Abstract : 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. READ MORE

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

   Author : Wen Jiang; Umeå universitet; []
   Keywords : 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;

   Abstract : 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.

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

   Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Separation of Pharmaceuticals by Capillary Electrophoresis using Partial Filling and Multiple-injections

   Author : Henrik Lodén; Curt Pettersson; Torbjörn Arvidsson; Ahmad Amini; Morgan Stefansson; Uppsala universitet; []
   Keywords : Capillary Coating; Chiral Separation; Enantiomers; Mass-spectrometric Detection; Method Validation; Multiple-injection Capillary Zone Electrophoresis; Non-aqueous Capillary Electrophoresis; Organic Solvents; Pharmaceutical Analysis; Quantitative Analysis;

   Abstract : Different multiple-injection methodologies and the partial filling technique (PFT) have been utilized for separation of pharmaceuticals by capillary elec-trophoresis. In multiple-injection capillary zone electrophoresis (MICZE), the samples and all standards, used for construction of the calibration curve, are analyzed within a single run. READ MORE
