  1. 1. Screening of HETP test conditions and resin storage solutions for HIC

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk farmaceutisk kemi

    Författare :Lise-Lotte Ronnerfors; [2023]
    Nyckelord :Hydrophobic Interaction Chromatography; Pfizer Health AB; Column packing;

    Sammanfattning : Hydrophobic interaction chromatography (HIC) is a common purification method for biological drug substances. For continuous monitoring the quality of the purification, a column performance test is carried out to test the packing of the resin. LÄS MER

  3. 2. Process and techno-economic analysis of a compact CO2 capture technology

    Master-uppsats, KTH/Energiprocesser

    Författare :Nestor Salvador Palacios; [2023]
    Nyckelord :Carbon capture; CO2 capture cost; compact system; packed column; potassium carbonate; Kolavskiljning; CO2 fångskostnad; kompakt system; packad kolonn; kaliumkarbonat;

    Sammanfattning : Den stora oron för de ökade växthusutsläppen och klimatförändringas effekter har uppmuntrat utvecklingen av åtgärder för att motverka de negativa konsekvenserna. En av de tekniker som har uppmärksammats under de senaste decennierna är kolavskiljningstekniken. LÄS MER

  4. 3. A novel approach for functionalising and separating Tröger's Base Analogues

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Emil Jakobsson; [2023]
    Nyckelord :Tröger s Base; Synthesis; Chromatography; Supramolecular chemistry; Diastereomers; Organic chemistry; Chemistry;

    Sammanfattning : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. LÄS MER

  5. 4. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Kejvan Ghofranpanah; [2022]
    Nyckelord :Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

    Sammanfattning : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.

  7. 5. Development and validation of sample clean-up using solid phase extraction prior oil spill fingerprinting

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Cheryl Loorents; [2022]
    Nyckelord :Oil spill; chemical fingerprint; solid phase extraction SPE ; development; validation.;

    Sammanfattning : In a forensic investigation involving oil, a comparative analysis named oil spill fingerprinting between a source and an oil spill is normally performed. It is based on detecting a certain selection of biomarkers with gas chromatography (GC) coupled to mass spectrometry (MS) which are later divided into diagnostic ratios (DRs). LÄS MER
