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

    Author : Kuria Ndung'u; Centrum för analys och syntes; []
    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.

  6. 4. Simplified Routines for Sample Preparation and Analysis of Chemical Warfare Agent Degradation Products

    Author : Raja Subramaniam; Calle Nilsson; Paula Vanninen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nerve agents; Alkyl alkylphosphonic acids; Solid phase derivatization; Fluorinated diazomethane reagent; High-energy collision induced dissociation; CID MS MS library; analytisk kemi; Analytical Chemistry;

    Abstract : The thesis describes the development of new and improved methods for analyzing degradation markers from organophosphorus Chemical Warfare Agents (CWAs). Paper I and II describes an innovative and significantly improved method for the enrichment, derivatization (trimethysilylation) and GC-MS analysis of a broad range of organophosphorus CWAs degradation markers, namely the alkylphosphonic acids and a zwitterionic compound.
