  2. 1. Packed Column Supercritical Fluid Chromatography : Applications in Environmental Chemistry

    Author : Nicole Riddell; Bert van Bavel; Robert McCrindle; Ingrid Ericson Jogsten; Jake Ryan; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supercritical Fluid Chromatography; Mass Spectrometry; Ionization; POPs; APPI; APCI; chiral; achiral; packed column;

    Abstract : Although gas and liquid chromatography have emerged as dominant separation techniques in environmental analytical chemistry, these methods do not allow for the concurrent analysis of chemically diverse groups of persistent organic pollutants (POPs). There are also a small number of compounds which are not easily amenable to either of these traditional separation techniques. READ MORE

  4. 2. Fundamental Investigations of Supercritical Fluid Chromatography

    Author : Martin Enmark; Torgny Fornstedt; Arvind Rajendran; Karlstads universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Fundamental research on supercritical fluid extraction kinetics : From on-line measurements to inverse modeling

    Author : Victor Abrahamsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supercritical fluid extraction; supercritical fluid chromatography; linseed; microalgae; extraction kinetics; inverse modeling; curve resolution;

    Abstract : Supercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. READ MORE

  6. 4. Extraction and chromatography of bioactive compounds in complex samples using supercritical CO2 technology

    Author : Said Alhamimi; Centrum för analys och syntes; []
    Keywords : Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

    Abstract : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. READ MORE
