  1. 16. Determination of the Environmental Fate of Drug Substances and the Matrix Effects of Complex Samples in SFC/ESI-MS

    Författare :Alfred Haglind; Curt Pettersson; Mikael Hedeland; Torbjörn Arvidsson; Deirdre Cabooter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SFC-MS; matrix effect; ion cluster; Supercritical fluid chromatography; ESI; chiral separation; transformation products; LC-QToF; wetland microcosms; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : Awareness of the potential problems caused by drug compounds in the environment has increased over the last decade, both among researchers and with the public. This thesis describes the development of analytical methods and their application to wetlands constructed for purification of wastewater from e.g. drug compounds. LÄS MER

  3. 17. Amino acids with relevance to health, climate and the environment : Development of mass spectrometric methods

  5. 19. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC

    Författare :Robert Arnell; Torgny Fornstedt; Andreas Seidel-Morgenstern; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Preparative LC; Chiral LC; Multi-component LC; Adsorption isotherm; Tracer-pulse method; Inverse method; Inverse method on plateaus; Peak deformations; Chiral drug-protein interactions; Analytisk kemi;

    Sammanfattning : This thesis concerns the development and validation of methods for characterization of multi-component preparative LC systems. Measurements of competitive adsorption isotherms are performed to gain detailed information about the interactions inside the chromatography column. LÄS MER
