Portable real-time quantitative mass spectrometry for multicomponent BVOCs and its application in field observations
(Yokohama City Univ.)
oKanako Sekimoto
Biogenic volatile organic compounds (BVOCs) emitted from plants occur in the atmosphere at very low concentrations, typically in the ppb-ppt range. These compounds play crucial roles in atmospheric chemistry as well as in chemical communication between plants and between plants and insects. However, comprehensive identification of BVOCs and quantitative evaluation of their impacts remain limited. To address these challenges, I have been developing a portable, quantitative mass spectrometric technique for multicomponent BVOCs. The method is based on proton-transfer-reaction mass spectrometry (PTR-MS) and incorporates my original approach that enables comprehensive quantification of BVOCs without the need for standard calibration curves. In this presentation, I will introduce the principles of this portable quantitative MS technique and present recent real-time observations of diverse BVOCs at forest sites.
