  1. 1. Characterizing Chromatography Media NMR-based Approaches

    Author : Fredrik Elwinger; István Furó; Stéphane Viel; []
    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

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

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Trifa Mohammad Ahmed; Roger Westerholm; Peter Haglund; [2015]
    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

  3. 3. Adsorption Studies with Liquid Chromatography Experimental Preparations for Thorough Determination of Adsorption Data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lena Edström; Jonas Bergquist; Lars Hagel; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid chromatography; HPLC; UHPLC; Reversed phase; Preparative chromatography; Adsorption isotherm; Injection profile; Sample pH; pH stable conditions; Peak deformation; Band distortion; Overloaded band; Chiral preparative chromatography; Analytical Chemistry; Analytisk kemi;

    Abstract : Analytical chemistry is a field with a vast variety of applications. A robust companion in the field is liquid chromatography, the method used in this thesis, which is an established workhorse and a versatile tool in many different disciplines. READ MORE

  4. 4. CALIBRATION OF CHROMATOGRAPHY MODELS

    University dissertation from Inst för Kemiteknik, Kemicentrum, Lunds Universitet

    Author : Patrik Persson; [2004]
    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

  5. 5. Fast isolation of proteins from bioreactors using affinity chromatography techniques

    University dissertation from Eva Pålsson, Tillämpad biokemi, Lunds universitet

    Author : Eva Pålsson; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; protein purification; analyses; dispersion; chromatography matrices; Biochemistry; Biokemi; Metabolism; expanded bed; metabolism; Biotechnology; Bioteknik;

    Abstract : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. READ MORE
