摘要
利用在线检测质谱仪(SPIMS-1000)分别对高温烘烤、长时间密封保存、机械损伤等处理过的松科松属马尾松(Pinus Massoniana L.)样品排放的挥发性有机物(VOCs)与新鲜样品进行对比检测。SPIMS-1000在线检测质谱仪能够检测出植物排放的异戊二烯(m/z 68)和单萜(m/z 136),及其它一些特异性组分,如(Z)-3-己烯醛(m/z 98)等。利用在线检测质谱仪实现敞开环境中原位植物排放气体的检测。实验表明,在线检测质谱仪被广泛应用于环境中VOCs的实时、在线、定性快速检测。
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.
