  3. 3. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices

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

    Author : Nahid Amini; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sample preparation; SPE; RAM; GCB µ-trap; GCB disk; High temperature LC; LC MS; ESI; APCI; Matrix effects; LIT-MS; SALDI; Sample screening; Oxidized GCB; Silicon nitride; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. READ MORE

  4. 4. Analysis and human levels of persistent perfluorinated chemicals

    University dissertation from Örebro : Örebro universitetsbibliotek

    Author : Anna Kärrman; Örebro universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOS; PFOA; SPE; LC-MS; human exposure; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Chemistry; Kemi;

    Abstract : An extensive use of perfluorinated chemicals (PFCs) in the last 50 years has resulted in a worldwide spread of these persistent chemicals. Human populations are subjected to a large number of PFCs in ways that are not yet fully explained. READ MORE

  5. 5. Strategies for Miniaturized Biomarker Detection

    Abstract : Popular Abstract in Swedish Prostatacancer är en av de vanligaste förekommande cancerformerna. Många äldre män har cancerceller i sin prostata, men som tur är behöver inte all cancer behandlas eftersom den inte växer. I USA får ungefär 27% av alla män prostatacancer och cirka 10% dör av det.
