    Sammanfattning : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. LÄS MER

  2. 2. Fundamental Investigations of Supercritical Fluid Chromatography

    Författare :Martin Enmark; Torgny Fornstedt; Arvind Rajendran; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supercritical Fluid Chromatography; SFC; Modeling; Adsorption Isotherms; Scale-up; Peak Distortion; Injection; Design of Experiments; Perturbation Peak Method; Elution by Characteristic Points Method; Method transfer; Kemi; Chemistry;

    Sammanfattning : This thesis aims at a deeper understanding of Supercritical FluidChromatography (SFC). Although preparative SFC has started to replace Liquid Chromatography (LC) in the pharmaceutical industry - because of its advantages in speed and its less environmental impact - fundamental understanding is still lacking.

  3. 3. Development of Methods for Phase System Characterization in Liquid Chromatography

    Författare :Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

    Sammanfattning : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. LÄS MER
