  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; analytisk kemi; Analytical Chemistry;

    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.

  4. 4. Application and Design Developments in Diffractive Optics

    University dissertation from Chalmers University of Technology

    Author : Mathias Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; diffractive optics; DOE; multichannel rotary joint; analog-to-digital converter; subwavelength grating; spatial light modulator SLM ; free-space optical interconnect; beam shaper; robust fan-out;

    Abstract : There has been strong development in the field of diffractive optics (DO) in research laboratories over the past two decades. Much progress has been made, both in design and analysis, as well as in manufacturing techniques. However, so far DO have only reached the market in small numbers. READ MORE

  5. 5. 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
