  2. 1. Liquid Chromatography Coupled to Mass Spectrometry : Implementation of Chemometric Optimization and Selected Applications

    Author : My Moberg; Jonas Bergquist; Karin E. Markides; Dan Bylund; Douglas B. Kell; Uppsala universitet; []
    Keywords : Analytical chemistry; liquid chromatography; mass spectrometry; tandem mass spectrometry; electrospray ionization; inductively coupled plasma; chemometrics; optimization; multivariate data analysis; design of experiments; response surface model; siderophore; azathioprine; peptide; Analytisk kemi;

    Abstract : Liquid chromatography (LC) coupled to mass spectrometry (MS) offers highly selective and sensitive analysis of a wide variety of compounds. However, the use of hyphenated experimental set-ups implies that many parameters may have an effect on the studied response. READ MORE

  4. 2. Characterizing Chromatography Media : NMR-based Approaches

    Author : Fredrik Elwinger; István Furó; Stéphane Viel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; nuclear magnetic resonance; NMR; self-diffusion; magic-angle spinning; quantitative; distribution coefficient; pore size; Kemi; Chemistry;

    Abstract : Liquid chromatography is an essential technique in manufacturing biopharmaceuticals where it is used on all scales from analytical applications in R&D to full-scale production. In chromatography the target molecule, typically a protein, is separated and purified from other components and contaminants. READ MORE

  5. 3. CALIBRATION OF CHROMATOGRAPHY MODELS

    Author : Patrik Persson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Abstract : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. READ MORE

  6. 4. Determination of OPAHs and PAHs in Particulate Matter from Ambient Air and Engine Emissions : Multidimensional Chromatography

    Author : Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : Particulate matter (PM) is an air pollutant that seriously impacts human health. Epidemiological studies have shown associations between human exposure to urban air PM and lung cancer, respiratory and cardiovascular diseases. READ MORE

  7. 5. Analytical method development in liquid chromatography- mass spectrometry based metabolomics

    Author : Ida Erngren; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Gérard Hopfgartner; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Analytical pharmaceutical chemistry; metabolomics; liquid chromatography; mass spectrometry; hydrophilic interaction liquid chromatography; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : Metabolomics is the analytical field which aims at analyzing all small molecules, metabolites, in a biological system simultaneously. Currently no analytical methods are able to capture the entire metabolome, therefore, the analytical methods are often developed to be as general as possible. READ MORE
