摘要:
This paper describes the preliminary study of a novel approach for the on-line analysis of volatile organic compounds (VOCs) emitted from plants by using a newly developed compact and mobile mass spectrometer (SPIMS-1000). In particular, VOCs emitted from branches and leaves of Pinus massoniana L. in different conditions (fresh, baked at high-temperature, seal preserved and mechanically damaged) were measured. Isoprene (m/z 68), monoterpenes (m/z 136), (Z)-3-hexenal (m/z 98) and some other VOCs were efficiently detected in-situ by using the on-line mass spectrometry. The results indicate that SPIMS-1000 has a great potential for the rapid and qualitative analysis on-line, in-situ, of VOCs emitted by plants in outdoor air.
