  4. 7. Acoustofluidic rare cell sample preparation

    Author : Maria Antfolk; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. READ MORE

  5. 8. On-line Sample Pretreatment Based on Membrane Enrichment, Mainly Using Supported Liquid Membranes, for Chromatographic Analysis

    Author : Yin Shen; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological Sample; Environmental Sample; Capillary Gas Chromatography; Ion Chromatography; Automation; Sample Pretreatment; Enrichment; Membrane; Extraction; Analytical chemistry; Analytisk kemi;

    Abstract : The main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. READ MORE

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

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

    Abstract : 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.
