  2. 1. Porous polymeric materials for chromatography : Synthesis, functionalization and characterization

    Author : Emil Byström; Knut Irgum; Camilla Viklund; Solomon Tesfalidet; Klaus K Unger; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; porous polymer monolith; pore size distribution; nitrogen sorptiometry; mercury intrusion porosimetry; scanning and transmission electron microscopy; plasma functionalization; Analytical chemistry; Analytisk kemi; Separation methods; Separationsmetoder; Polymer chemistry; Polymerkemi; analytisk kemi; Analytical Chemistry;

    Abstract : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.

  5. 3. 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
