  1. 1. Applications of chemometric methods in optical spectroscopy

    Författare :Jan Nygren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : .... LÄS MER

  3. 2. Development and Applications of Chemometric Methods for Spectral Deconvolution

    Författare :Robert Sjöback; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Chemometric methods are very useful in analyzing complex mixtures. In this thesis two methods are presented that allow resolution of overlapping spectra from mixtures without knowledge of the pure component spectra. It also includes applications of these methods, in which the spectroscopic properties of the fluorescein system are characterized. LÄS MER

    Sammanfattning : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. LÄS MER

  5. 4. Chemometric methods for analysis of spectroscopic data from batch process monitoring

    Författare :Erik Furusjö; KTH; []
    Nyckelord :in situ spectroscopy; reaction monitoring; organic synthesis; solubility; crystallization; multivariate calibration; curve resolution; kinetic model; reaction rate constant; activation energy; target testing; bootstrap;

    Sammanfattning : Understanding of a process is essential for processdevelopment, optimisation and scale-up. In situ spectroscopy isan attractive measurement technique that can increase processunderstanding, since samples need not be retrieved from theprocess mixture. LÄS MER
