  3. 2. Study of retention mechanisms in Hydrophilic Interaction Chromatography by Nuclear Magnetic Resonance Spectroscopy

    Författare :Adel Shamshir; Knut Irgum; Tobias Jonsson; Ngoc Phuoc Dinh; Torgny Fornstedt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HILIC; hydrophilic interaction chromatography; adsorption; STD-NMR; saturation transfer difference; retention mechanism; NMRD; solid state-NMR; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis deals with investigations of the retention mechanisms in hydrophilic interaction liquid chromatography (HILIC) using nuclear magnetic resonance spectroscopy. The aims are to understand how the different types of stationary phases can influence the retention of various solutes and the adsorption abilities of solvent on stationary phases. LÄS MER

  4. 3. Spectroscopic data and multivariate analysis : tools to study genetic perturbations in poplar trees

    Sammanfattning : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. LÄS MER
