  2. 1. The practice and utility of the Shpol'skii effect in chemical analysis

    Author : Anders Colmsjö; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is an attempt to establish the Shpol' skii fluorescence as a valuable tool for analytical chemists. The basic principles of the Shpol'- skii fluorescence is comprehensively explained and the most important parameters that influence the registering of quasilinear spectra are discussed. READ MORE

  4. 2. New Tools for Trapping and Separation in Gas Chromatography and Dielectrophoresis : Improved Performance by Aid of Computer Simulation

    Author : Fredrik Aldaeus; Anders Colmsjö; Marja-Liisa Riekkola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; dielectrophoresis; computer simulation; finite element method; trapping; separation; lab-on-a-chip; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Computer simulations can be useful aids for both developing new analytical methods and enhancing the performance of existing techniques. This thesis is based on studies in which computer simulations were key elements in the development of several new tools for use in gas chromatography and dielectrophoresis. READ MORE

  5. 3. Novel Microextraction Techniques for Bioanalysis of Neurotransmitters and Biomarkers in Biological Fluids

    Author : Aziza El Beqqali; Mohamed AbdelRehim; Anders Colmsjö; Lennart Mathiasson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : Sample preparation (sample pre-treatment) is the initial step and an essential part in bioanalysis procedure. The main role of sample preparation is to extract and transfer the analyte(s) of interest from a complex matrix to a purified media such as a pure solvent for analysis and quantification. READ MORE

  6. 4. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics

    Author : Henrik Kempe; Anders Colmsjö; Ulrika Nilsson; Jan Åke Jönsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Parameter estimation; Diffusion; Molecularly imprinted polymer; Suspension polymerization; Chemometrics; Analytical chemistry; Analytisk kemi;

    Abstract : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. READ MORE

  7. 5. Development of Field-adapted Analytical Methods for the Determination of New Antimalarial Drugs in Biological Fluids
