  1. 1. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Författare :Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. LÄS MER

  2. 2. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

    Författare :Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

    Sammanfattning : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. LÄS MER

  4. 4. Interfacing HPLC with MALDI- and ESI-MS for Automated High Sensitivity Analysis of Proteins and Peptides

    Författare :Tasso Miliotis; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; automated; phosphorylation; ZAP-70; peptides; proteins; comprehensive; multidimensional; two-dimensional; piezoelectric; microdispenser; flow-through; ESI-MS MS; Capillary HPLC; MALDI-TOF MS; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides.
