2. 1. 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

4. 2. Retention time predictions in Gas Chromatography

   Author : Yasar Thewalim; Anders Colmsjö; Torgny Fornstedt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; computer simulation; two-parameter model; retention time prediction; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Abstract : In gas chromatography, analytes are separated by differences in their partition between a mobile phase and a stationary phase. Temperature-program, column dimensions, stationary and mobile phases, and flow rate are all parameters that can affect the quality of the separation in gas chromatography. READ MORE

5. 3. Metal film growth on weakly-interacting substrates : Stochastic simulations and analytical modelling

   Author : Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Pär Olsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Thin films are nanoscale layers of material, with exotic properties useful in diverse areas, ranging from biomedicine to nanoelectronics and surface protection. Film properties are not only determined by their chemical composition, but also by their microstructure and roughness, features that depend crucially on the growth process due to the inherent out-of equilibrium nature of the film deposition techniques.

6. 4. 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

7. 5. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations

   Author : Saara Mikkonen; Åsa Emmer; Leopold Ilag; Jenny Ottosson Takanen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Preconcentration; open microchannel; microchip; MALDI; electrospray ionization; nanoelectrospray; mass spectrometry; computer simulation;

   Abstract : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).
