| 摘要 |
The present invention relates to profiles (significant set) of volatile organic compounds, VOCs, namely hydrocarbons between 2 and 24 carbon atoms (C2-C24), using solid phase microextraction (SPME) and high resolution gas chromatography coupled to mass spectrometry (GC-MS) as methodology. The present invention provides the identification and characterization of profiles of cellulosic material, markers of degradation and/or ageing of cultural heritage, or the identification and characterization of profiles of biological fluids, markers of pathology. The present invention provides the identification and characterization of the hydrocarbons, chemical components of the profiles, markers of chemical degradation of cellulosic polymer or of lipid peroxidation due to pathology.
