Sensitivity, repeatability, reproducibility and accuracy were investigated. READ MORE

  3. 3. Analysis of Acrylamide and Anthocyanins in Foods Extraction Optimization for Challenging Analytes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik V. Petersson; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analysis; Extraction; Optimization; Acrylamide; Anthocyanins; Foods; Challenges; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Analytical Chemistry; Analytisk kemi;

    Abstract : In this thesis, the main concern has been to improve the reliability of different parts of the analytical workflow (Paper I, II, IV &V). Additionally, one of the resulting optimized methods was used in a real application (Paper III).Paper I-II concerned the extraction of acrylamide (AA) from foods. READ MORE

  4. 4. Analytical Aspects of Atmospheric Pressure Ionisation in Mass Spectrometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : C. Fredrik Bökman; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The actual signal recorded with an analytical instrument is not always a true reflection of the analysed sample. In this thesis a further insight of the atmospheric pressure ionisation processes electrospray (ESI) and atmospheric pressure chemical ionisation (APCI) has been endeavoured, to provide a deeper understanding of and ways to minimize this bias.
