  1. 1. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Solal GAUDIN; [2023]
    Nyckelord :Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

    Sammanfattning : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. LÄS MER

  3. 2. Building an in-house spectral library using GCorbitrap HRMS

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Elias Kolsmyr; [2022]
    Nyckelord :Environmental contaminants; Plastic additives; Gas chromatography; High resolution mass spectrometry; Spectral library; MS-DIAL;

    Sammanfattning : There are a great variety of environmentals contaminants, a lot of which are understudied asit is today. The aim of this study was to develop an in-house high-resolution spectral librarycontaining environmental contaminants, with focus on plastic additives. The spectral librarywould then be used to perform suspect screening on real sample extracts. LÄS MER

  4. 3. Non-target screening of sediment samples fromthe Canadian Arctic: comparing two different gas chromatography – high resolution mass spectrometry (GC-HRMS) techniques

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Mathilda Timner; [2022]
    Nyckelord :Arctic marine sediment ׀ GC×GC-HR-ToF-MS ׀ GC-Orbitrap-MS ׀ Identification ׀ Non-target screening ׀ Organic pollutants;

    Sammanfattning : Since the late 18th century, chemicals have been industrially produced, and used by consumers. Today, the number of registered chemicals are over 150 000 in North America and Europe alone, and the number is predicted to increase. LÄS MER

  5. 4. Mass Spectrometry Based Proteomics : Toward understanding neuropathic pain

    Master-uppsats, Uppsala universitet/Analytisk kemi; Uppsala universitet/Institutionen för kemi - Ångström; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Eleni Gkanatsiou; [2016]
    Nyckelord :neuropathic pain; mass spectrometry based proteomics; explorative proteomics;

    Sammanfattning : The aim of this project was to get insight into mass spectrometry based proteomics, get familiarized with novel techniques, and obtain the operating skills with modern Orbitrap mass spectrometers. In order to achieve this, the proteome changes in neuropathic pain responses corresponding to nerve injury side in individual rat’s spinal cord were explored. LÄS MER

  7. 5. Method Development in Mass Spectrometry-based Proteomics for Determination of Early Pregnancy in Dogs

    Master-uppsats, Uppsala universitet/Analytisk kemi

    Författare :Sebastian Lindersson; [2016]
    Nyckelord :mass spectrometry; proteomics; orbitrap; canine pregnancy; CRP;

    Sammanfattning : This project is concerned with method development in mass spectrometry (MS)-based proteomics in order to find putative biomarkers for early pregnancy ofdomesticated dogs. It is of importance for dog breeders to know whether the dogsbecome pregnant post-mating. LÄS MER
