  1. 1. Exploratory study of ion pair liquid chromatography separation methods and sample preparation procedures – for quantification of amount 5’capped and uncapped mRNA

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

    Författare :Felicia Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Using ion pair chromatography, separation and analysis of shorter mRNA fragments was possible. The aim of the study was to develop a separation method for quantitation of 5’capped versus uncapped mRNA. Cleavage of mRNA was performed by complementary probes and the enzyme RNase H which created shorter mRNA fragments containing the 5’ end. LÄS MER

  5. 4. 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

  7. 5. Characterization of absorption spectra of molecular constituents in the mid-infrared region and their role as potential markers for breath analysis

    Kandidat-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Mikael Karlsson; [2014]
    Nyckelord :;

    Sammanfattning : The use of exhaled breath analysis in assessing the health status of human individuals is an intriguing concept that has attracted more and more attention during recent years. Although detection of species in breath can, to a certain extent, be made by both electrochemical and mass spectrometric techniques, these do not always provide sufficient sensitivity, selectivity and speed.
