Acquisition of Proton Transfer Reaction Mass Spectrometer for the Environmental Research Facility of Biosphere 2 Center, Columbia University

哥伦比亚大学生物圈2号中心将获得一个质子转移反应质谱仪（PTR-MS）和一个气相色谱飞行时间质谱仪（GC-TOFMS），以支持化学生态学和生物圈-大气化学领域的跨学科合作研究议程。该设备将加强许多领域的研究，包括a)昆虫神经生物学中宿主植物挥发性有机化合物（VOCs）和二氧化碳排放的研究；B)泛热带蚂蚁的化学通讯和防御分析；c)受植物挥发性有机化合物排放影响的生物圈-大气化学在线测量；D)了解植物释放的异戊二烯在（昆虫）化学生态学中的作用；e)离子迁移谱的发展。质谱（MS）是一种用于探测内部结构细节和获得大量有机、生物有机和有机金属分子的分子组成的技术。这些研究的结果将对包括化学生态学和大气科学在内的许多领域产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Biosphere 2 Center at Columbia University will acquire a Proton Transfer Reaction Mass Spectrometer (PTR-MS) and a gas chromatography-time of flight mass spectrometer (GC-TOFMS) to support a collaborative, interdisciplinary research agenda in chemical ecology and biosphere-atmosphere chemistry. This equipment will enhance research in a number of areas including a) investigations of host-plant volatile organic compounds (VOCs) and CO2 emissions in insect neurobiology; b) analysis of chemical communication and defense in a pantropical ant; c) on-line measurements of biosphere-atmosphere chemistry influenced by plant emission of VOCs; d) understanding the role of plant-emitted isoprene in (insect) chemical ecology; and e) ion mobility spectroscopy development. Mass spectrometry (MS) is a technique used to probe intimate structural details and to obtain the molecular compositions of a vast array of organic, bioorganic, and organometallic molecules. The results from these studies will have an impact in a number of areas including chemical ecology and atmospheric sciences.
