  2. 1. Capillary electroseparations with mass spectrometric detection Nanoparticle-based continuous full filling and applications for complex sample matrices

    Author : Peter Viberg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; phthalates; continuous full filling; heterocyclic aromatic amines; pseudostationary phase; capillary electrophoresis; electrokinetic chromatography; capillary electrochromatography; nanoelectrospray; mass spectrometry;

    Abstract : One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. READ MORE

  4. 2. Nanoparticle-based Capillary Electrochromatography - Separation of Small Molecules and Proteins

    Author : Christian Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Capillary Electrochromatography; Green Fluorescent protein; Pseudostationary Phase; Capillary Electrophoresis;

    Abstract : The use of nanoparticle-based pseudostationary phases (PSPs) in capillary electrochromatography (CEC) for separation of small molecules and proteins is demonstrated. A continuous full filling approach is used where the nanoparticles are suspended in the electrolyte. READ MORE

  5. 3. Nanoparticles in capillary electrophoresis : what are the benefits?

    Author : David Malmström; Jonas Bergquist; Charlotta Turner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : 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. READ MORE

  6. 4. Nanoparticle-based capillary electrochromatography

    Author : Peter Spégel; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Analytisk kemi; Analytical chemistry; Nanoparticles; Molecularly imprinted polymers; Capillary electrochromatography;

    Abstract : This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. READ MORE

  7. 5. Molecularly Imprinted Matrices for Electrochromatography

    Author : Leif Schweitz; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; capillary electrophoresis; enantiomer; film coating; microparticle; continuous bed; monolith; molecular imprinting; capillary electrochromatography; Kemiteknik och kemisk teknologi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. READ MORE
