  4. 17. New approaches to preparation of macroporous monoliths for use in liquid chromatography

    Author : Anh Mai Nguyen; Knut Irgum; Tatiana B. Tennikova; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; monolith; polycondensation; dissolution-precipitation; epoxy-amine; poly-amide; nylon; emulsion polymerization; characterization; protein separation; liquid chromatography; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. READ MORE

    Abstract : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.

  6. 19. Efficient algorithms for highly automated evaluation of liquid chromatography - mass spectrometry data

    Author : Mattias Fredriksson; Dan Bylund; Patrik Petersson; Bengt-Olof Axelsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Digital filtering; Liquid chromatography; Mass spectrometry; Method; Chemistry; Kemi;

    Abstract : Liquid chromatography coupled to mass spectrometry (LC‐MS) has due to its superiorresolving capabilities become one of the most common analytical instruments fordetermining the constituents in an unknown sample. Each type of sample requires a specificset‐up of the instrument parameters, a procedure referred to as method development. READ MORE

  7. 20. Analysis of Complex Biological Samples using Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
