This project involved the development and application of a proton-transfer-reaction mass spectrometry (PTR-MS) for on-line detection and identification of volatile organic compounds (VOCs) for the analysis of primary and secondary biogenic carbonyls in complex VOC mixtures released from vegetation. The new instrument, a proton-transfer ion trap mass spectrometry (PT-ITMS) instrument, will be developed for used in both field and airborne platforms for continuous, simultaneous analysis of important VOCs and their carbonyl oxidation products. VOCs released from vegetation may have a major impact on the oxidative capacity of the atmosphere and in the formation of ozone and aerosols.

该项目涉及质子转移反应质谱（PTR-MS）的开发和应用，用于在线检测和鉴定挥发性有机化合物（VOCs），以分析从植物释放的复杂VOC混合物中的初级和次级生物羰基化合物。 新的仪器，质子转移离子阱质谱仪（PT-ITMS）仪器，将开发用于现场和机载平台的连续，同时分析重要的挥发性有机化合物及其羰基氧化产物。 植物释放的挥发性有机化合物可能对大气的氧化能力以及臭氧和气溶胶的形成产生重大影响。
