Reactions in an Ion Trap to Improve On-line Volatile Organic Compound (VOC) and Oxygenated Volatile Organic Compound (OVOC) Measurements

本项目探讨了一种创新的在线分析挥发性有机化合物（VOCs）及其氧化产物的新方法的可行性。 在加州-戴维斯大学和北卡罗来纳州大学的研究人员之间的一个合作项目中，将对大气采样辉光放电电离/四极离子阱质谱仪（ASGDI/QITMS）进行修改，然后在一些实验室实验中进行挑战，以量化代表周围自然大气水平的VOC和含氧VOC的灵敏度和选择性。 该项目的更广泛影响包括展示一种潜在的创新新技术，用于选择性测量在环境光氧化循环、臭氧和二次气溶胶形成、人类健康和可居住性以及气候中发挥关键作用的各种至关重要的化合物。 该项目支持研究生的全职指导研究工作。

This project explores the feasibility of an innovative new on-line analysis method for volatile organic compounds (VOCs) and their oxidation products. In a collaborative project between investigators at University of California - Davis and University of North Carolina an atmospheric sampling glow-discharge ionization/quadrupole ion trap mass spectrometer (ASGDI/QITMS) will be modified then challenged in a number of laboratory experiments to quantify sensitivity to and selectivity of VOCs and oxygenated VOCs at levels representative of the ambient natural atmosphere. The broader impact of this project involves demonstration of a potentially innovative new technique for selective measurement of a variety of critically important compounds playing key roles in ambient photooxidation cycles; ozone and secondary aerosol formation; human health and habitability; and climate. The full-time directed research work of a graduate student is supported by the project.
