  4. 2. Adsorption Isotherm Parameter Estimation in Nonlinear Liquid Chromatography

    Author : Patrik Forssén; Bertil Gustafsson; Torgny Fornstedt; Georges Guiochon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High performance liquid chromatography HPLC ; Preparative chromatography; Competitive adsorption isotherm parameters; Perturbation peak PP method; Inverse method IM ; Computer simulation; Parameter estimation; Numerical method; Scientific Computing; Beräkningsvetenskap;

    Abstract : This thesis concerns the development and validation of methods for the industrially important area of adsorption isotherm parameter estimation in preparative, nonlinear high performance liquid chromatography (HPLC). Preparative chromatography is a powerful separation method to get pure compounds from more or less complex liquid mixtures, e.g. READ MORE

  6. 4. High-performance liquid chromatography for analysis of 32P-postlabeled DNA adducts

    Author : Magnus Zeisig; Karolinska Institutet; Karolinska Institutet; []
    Keywords : DNA adducts; 32P-postlabeling; HPLC; method development;

    Abstract : The formation of DNA adducts, i.e. the covalent binding of chemicals and chemical groups to DNA, is believed to be an important step in chemical carciogenesis. DNA adducts are usually formed at very low levels which requires very sensitive methods to analyze them. READ MORE

  7. 5. Development and Validation of HPLC Methods for Analytical and Preparative Purposes
