  1. 1. Essentially Lipids : Analytical methods for the characterization of lipid materials

    Författare :Petter Olsson; Bengt Herslöf; Jan Holmbäck; Torgny Fornstedt; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lipids; Chromatography; HPLC; Charged Aerosol Detection; Evaporative light scattering detection; mass spectrometry; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis describes analytical methods for chromatographic characterizations of lipids in biological and technical systems.Lipids are a group of compounds with a central role in all known forms of life. In addition to the biological roles, lipids are also components in many products of our daily usage. LÄS MER

    Sammanfattning : Three micro detectors were developed and studied using micro-liquidchromatography (micro-LC). An evaporative light scattering detector (ELSD) nebulizer was developed for use with flow rates ranging from 0.5 to 10 µL/min. LÄS MER

  4. 4. Development of analytical methods for determination of drugs, used against tropical diseases, in biological fluids

    Författare :Mikaela Malm; Högskolan Dalarna; []
    Nyckelord :;

    Sammanfattning : The overall aim of this thesis was to develop analytical methods for determination of drugs, used against tropical diseases, in biological fluids. For the treatment of malaria, piperaquine (PQ) is used in combination with another antimalarial. LÄS MER

  5. 5. Analysis of lipids by supercritical fluid chromatography

    Författare :Mustafa Demirbüker; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis is described the development of new metods for the analysis of triacylglycerols and fatty acid methyl esters by supercritical fluid chromatography. Packed micro columns have been utilized for SFC and the properties of different types of packing materials have been evaluated. LÄS MER
