  1. 1. Cold trapping and reinjection techniques for gas chromatography-mass spectrometry

    Author : Sven P. Jacobsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes the use of cold trapping and reinjection techniques in combination with gas chromatography-mass spectrometry. A summary of different cold trap/ reinjection systems is presented. READ MORE

  2. 2. Processing and analysis of NMR data : Impurity determination and metabolic profiling

    Author : Jenny Forshed; Sven P. Jacobsson; Jules L. Griffin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative nuclear magnetic resonance spectrometry; qNMR; multivariate analysis; peak alignment; data fusion; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis describes the use of nuclear magnetic resonance (NMR) spectrometry as an analytical tool. The theory of NMR spectroscopy in general and quantitative NMR spectrometry (qNMR) in particular is described and the instrumental properties and parameter setups for qNMR measurements are discussed.

  4. 4. Novel on-line mid infrared detection strategies in capillary electrophoretic systems

    Author : Malin Kölhed; Bo Karlberg; Sven P. Jacobsson; Andre' J. Sommer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; on-line hyphenation; mid infrared detection; capillary electrophoresis; FTIR; quantum cascade laser; aqueous samples; Analytical chemistry; Analytisk kemi;

    Abstract : Infrared absorption spectra can provide analytically useful information on a large variety of compounds, ranging from small ions to large biological molecules. In fact, all analytes that possess a dipole moment that changes during vibration are infrared-active. The infrared (IR) spectrum can be subdivided into far-, mid- and near- regions. READ MORE
