  2. 21. Mycotoxins in indoor environments. Determination using mass spectrometry

    Author : Erica Bloom; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Abstract : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. READ MORE

  4. 22. Data analysis of non-targeted mass spectrometry experiments

    Author : Erik Tengstrand; Magnus Åberg; Olav Kvalheim; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Chemometrics; mass spectrometry; HPLC; metabolomics; Analytical Chemistry; analytisk kemi;

    Abstract : Data processing tools are valuable to the analytical chemist as they can speed up the analysis, and sometimes solve problems that are not feasible to solve in a traditional manner. However, the complexity of many data processing tools can make their use daunting for the inexperienced user. READ MORE

  5. 23. Improved mass accuracy in MALDI-TOF-MS analysis

    Author : Martin Kempka; Johan Roeraade; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; MALDI; mass spectrometry; mass accuracy; peak picking; ion formation; proteins; peptides; chip; sample handling; sensitivity.; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. READ MORE

  6. 24. High-throughput protein analysis using mass spectrometry-based methods

    Author : Tove Boström; Sophia Hober; Thomas Laurell; Ole N. Jensen; KTH; []
    Keywords : Proteomics; mass spectrometry; affinity proteomics; immunoenrichment; immunoprecipitation; IMAC; screening; protein production; protein purification; ISET; quantification; SILAC; stable isotope standard; antibody validation; Bioteknologi; Biotechnology;

    Abstract : In the field of proteomics, proteins are analyzed and quantified in high numbers. Protein analysis is of great importance and can for example generate information regarding protein function and involvement in disease. Different strategies for protein analysis and quan- tification have emerged, suitable for different applications. READ MORE

  7. 25. Mass spectrometry based analysis of endogenous sterols and hormones
