    Sammanfattning : Adverse health effects have been linked to exposure to particulate matter, and wood combustion is considered as an important source of harmful particulate matter in the urban air and environment. Hydroxylated polycyclic aromatic hydrocarbons are a group of compounds with toxic, endocrine disrupting and carcinogenic properties. LÄS MER

  2. 2. Nanoparticles in capillary electrophoresis what are the benefits?

    Detta är en avhandling från Uppsala : Institutionen för fysikalisk och analytisk kemi, Uppsala universitet

    Författare :David Malmström; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : Capillary electrophoresis is a technique that separate compounds based on charge and size. During the last two decades capillary electrophoresis (CE) and mass spectrometry (MS) has gained in interest, become more robust to use and able to separate neutral analytes. LÄS MER
