  2. 2. Hydrophilic Separation Materials for Liquid Chromatography

    University dissertation from Umeå : Kemi

    Author : Petrus Hemström; Umeå universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; HILIC; Hydrophilic; Stationary phase; NATURAL SCIENCES Chemistry; NATURVETENSKAP 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

  3. 3. Liquid Chromatography Coupled to Mass Spectrometry Implementation of Chemometric Optimization and Selected Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis
