  1. 11. Discontinuous Galerkin Method for Liquid Chromatography Modelling

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Culligan; [2022]
    Keywords : ;

    Abstract : Chromatography is a separation technique used predominantly by the medical industry in purification and extraction of components in a solution. The setup is a column filled with resin particles where a solution of two components is filtered and separated due to different rates of interaction with the resin particles. READ MORE

  3. 12. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study

    University essay from Lunds universitet/Kemiska institutionen

    Author : Thi Hoai Thu Trinh; [2022]
    Keywords : dye-affinity chromatography; single-layer cryogels; double-layer cryogels; protein purification; bovine serum albumin; biochemistry; Chemistry;

    Abstract : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. READ MORE

  4. 13. Analytical Methods for High Molecular Weight UV Stabilizers

    University essay from KTH/Kemi

    Author : Elin Ljungström; [2022]
    Keywords : hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

    Abstract : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). READ MORE

  5. 14. Development and validation of an ultrahigh-performance liquid chromatography method for identity, assay and impurity testing of nicotine and preservatives in nicotine nasal spray

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Amane Kandas; [2021]
    Keywords : Nicotine; Nicotine nasal spray; Ultrahigh-performance liquid chromatography; Development; Validation; Technical analytical chemistry; Chemistry;

    Abstract : The topic of this study is to develop and validate an analysis method of nicotine nasal spray produced at McNeil AB. When developing the analysis method, several parameters were determined in advance to make the method more similar to other analysis methods at the company, making it more practical. READ MORE

  6. 15. Pressure-based clog detection in SPE-columns

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Elias Johansson; [2021]
    Keywords : Solid-phase extraction; SPE; Biotage; Extrahera; Analytical chemistry; Life-science; Medtech; Analytisk kemi; Naturvetenskap; Kemi;

    Abstract : The concept of integrated sensors in the Biotage® Extrahera™ system to perform live-monitoring of pressure inside SPE-columns is investigated. A test-rig containing the components necessary to simulate the pressure-cycle in the system is constructed and a printed-circuit board assembly is designed and implemented into its 24-column format.
