  5. 3. Hydrophilic Separation Materials for Liquid Chromatography

    Author : Petrus Hemström; Knut Irgum; Peter Schoenmakers; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; HILIC; Hydrophilic; Stationary phase; Chemistry; Kemi;

    Abstract : The main focus of this thesis is on hydrophilic interaction chromatography (HILIC) and the preparation of stationary phases for HILIC. The mechanism of HILIC is also discussed; a large part of the discussion has been adapted from a review written by me and professor Irgum for the Journal of Separation Science (ref 34). READ MORE

    Abstract : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. READ MORE

  7. 5. 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
