  2. 1. Nanoparticle-based Capillary Electrochromatography - Separation of Small Molecules and Proteins

    Author : Christian Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Capillary Electrochromatography; Green Fluorescent protein; Pseudostationary Phase; Capillary Electrophoresis;

    Abstract : The use of nanoparticle-based pseudostationary phases (PSPs) in capillary electrochromatography (CEC) for separation of small molecules and proteins is demonstrated. A continuous full filling approach is used where the nanoparticles are suspended in the electrolyte. READ MORE

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

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

    Abstract : 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.

  5. 3. Capillary electroseparations with mass spectrometric detection Nanoparticle-based continuous full filling and applications for complex sample matrices

    Author : Peter Viberg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; phthalates; continuous full filling; heterocyclic aromatic amines; pseudostationary phase; capillary electrophoresis; electrokinetic chromatography; capillary electrochromatography; nanoelectrospray; mass spectrometry;

    Abstract : One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. READ MORE

  6. 4. Electrochromatography and liquid chromatography : Microtechniques, instrumentation and applications

    Author : Christer Ericson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The thesis focuses on the design of efficient chromatographic and electrochromatographic microcolumns where a continuous bed is polymerized in situ in a capillary or a channel in a microchip device. In our technique, a solution of selected monomers is simply sucked or pressed into the capillary or microchip channel for subsequent polymerization. READ MORE

  7. 5. New Techniques for Chiral Separations

    Author : Jeanette Olsson; Lars Blomberg; Steen Honoré Hansen; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; analytical chemistry; chiral separation; GC; CE; CEC; Analytical chemistry; Analytisk kemi; Kemi; Chemistry;

    Abstract : Gas chromatography (GC) has been utilized for the study of enantiomer resolution of the atropisomers of PCBs, o,p´-DDD and o,p´-DDT. Different substituents and concentrations of cyclodextrin, capillary dimensions and type of stationary phase films have been investigated to achieve the resolution of as many of the atropisomers on one column as possible.
