  1. 1. A Novel Miniaturised Dynamic Hollow-Fibre Liquid-Phase Micro-Extraction Method for Xenobiotics in Human Plasma Samples

    University dissertation from Stockholm : Department of Analytical Chemistry, Stockholm University

    Author : Helena Hansson; Stockholms universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sample clean-up; human blood plasma; hollow-fibre liquid phase microextraction; supported liquid membrane extraction; SLM; HF-LPME; sample preparation; bioanalysis; liquid-liquid extraction; MEDICINE Chemistry; MEDICIN Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. READ MORE

  2. 2. Liquid Membrane Techniques for Trace Metal Analysis and Speciation in Environmental and Biological Matrices

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Kuria Ndung'u; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Pb and Organotin species; MMLLE; SLM; GC MS; PSA; GFAS; FAAS; ICP-MS; Speciation; DEHPA; Aliquat-336; trace metals; Cr III ; Cr VI ; Analytisk kemi;

    Abstract : In this thesis, liquid-membrane-based methods for the analysis of trace metal species in samples of environmental and biological origin were developed. By incorporating extracting reagents in the membrane liquid, trace metal ions were selectively separated from humic-rich natural waters and urine samples, prior to their determination using various instrumental techniques.

  3. 3. Surface Sampling and Automated Liquid Membrane Extraction of Fungicides

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Margareta Sandahl; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural water analysis; microporous membrane liquid-liquid extraction MMLLE ; supported liquid membrane SLM extraction; Dislodgeable fungicide residues; surface sampling; automated sample preparation for HPLC; Analytical chemistry; Analytisk kemi;

    Abstract : A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. READ MORE

  4. 4. Procedures for Sample Clean-up and Concentration in Capillary Zone Electrophoresis for Determination of Drugs in Biosamples

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Sveinbjörg Pálmarsdóttir; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi;

    Abstract : Procedures for sample clean-up and concentration in Capillary Zone Electrophoresis (CZE) have been developed for determination of drugs in biosample s. An on-capillary concentration technique based on enhanced field strengths, the double stacking procedure is introduced. READ MORE

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

    University dissertation from Department of Analytical Chemistry, Lund University
