1. 1. Characterizing Chromatography Media : NMR-based Approaches

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

   Sammanfattning : 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. LÄS MER

3. 2. Fast isolation of proteins from bioreactors using affinity chromatography techniques

   Författare :Eva Pålsson; Avdelningen för klinisk genetik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatography; protein purification; analyses; dispersion; chromatography matrices; Biochemistry; Biokemi; Metabolism; expanded bed; metabolism; Biotechnology; Bioteknik;

   Sammanfattning : 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. LÄS MER

4. 3. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

   Författare :Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

   Sammanfattning : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. LÄS MER

5. 4. Modeling and Optimization of Rare Earth Element Chromatography

   Författare :Mark Max-Hansen; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rare Earth Elements; Chromatography; Modeling; Optimization;

   Sammanfattning : The Rare Earth Elements are a group of metals, that are of growing technical and economical importance. Current separation techniques can be detrimental to the environment, and a clean technology for separation has been devised, based on analytical chromatography of the REEs. LÄS MER
