  1. 6. Strategy for Monitoring Organic Pollutants in Waste Water with Focus on Improved Sample Preparation

    Författare :Staffan Bergström; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Miljökemi; Environmental chemistry; Analytisk kemi; Analytical chemistry; Membrane extraction; Sample preparation; Organic pollutants; Monitoring strategy; Landfill leachate;

    Sammanfattning : Strategy and methodology is presented for the analysis of organic pollutants, with the purpose of evaluating treatment procedures for landfill leachate. Today, many investigations of treatment procedures are focusing on the measurement of water quality parameters such as chemical and biochemical oxygen demand, (COD and BOD), and total organic carbon, (TOC) when assessing the organic compounds in waste waters.

  5. 9. Improved Techniques for Protein Analysis Focusing on Membrane Proteins and Hydrophobic Peptides

    Författare :Theres Redeby; Åsa Emmer; Jonas ergquist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integral membrane proteins; Hydrophobic peptides; Sample handling; MALDI-TOF-MS; Structured sample support; CE; fraction collection; microchannel; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis, the vital cell functions performed by integral membrane proteins (IMPs) are briefly discussed. Such proteins are under-represented in most protein studies due to the hydrophobic nature of IMPs, which seriously complicate their solubilization, sample handling, preparation, separation and analysis.

  7. 10. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides

    Författare :Andreas Dahlin; Jonas Bergquist; Karin E. Markides; Robert T. Kennedy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Neuropeptides; Microchip; Enhanced microdialysis; Poly dimethylsiloxane PDMS ; Electrospray ionization ESI ; Multidimensional separation; Electrochemical manipulation; Mass spectrometry MS ; Capillary electrophoresis CE ; Microdevice; Microfabrication; Micro total analysis system μ-TAS ; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. LÄS MER
