    Abstract : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. READ MORE

  5. 5. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University
