    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; large volume injection; hyphenated techniques; LC-GC; GC-MS; mass spectrometry; GC; gas chromatography; carbazoles; PBDE; polybrominated diphenyl ethers; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis is based on studies in which the suitability of various gas chromatography (GC) injection techniques was examined for the determination of polybrominated diphenyl ethers (PBDEs) and carbazoles, two groups of compounds that are thermally labile and/or have high boiling-points. For such substances, it is essential to introduce the samples into the GC system in an appropriate way to avoid degradation and other potential problems. LÄS MER

    Författare :Axel Nordin; Innovation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical engineering design; industrial design; customization; optimization; Morphological repertoire; constraint handling; production; genetic algorithm; voronoi diagram; Renaissance 2.0;

    Sammanfattning : The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. LÄS MER
