NSF Young Investigator: Mass Spectrometric Characterization of Atmospheric Aerosol Particles

这个国家科学基金会青年研究员项目是在分析化学的一般领域，特别侧重于环境相关气溶胶的表征。在该奖项的五年任期内，普拉瑟教授和她的学生将对气溶胶颗粒进行基础研究，这些颗粒被认为参与了一些对环境重要的反应。单个颗粒的大小和组成使用激光门控系统结合激光解吸和飞行时间质谱法进行测量。将研究由无机盐和多芳烃组成的颗粒。目标是确定在控制大气反应中重要的粒子特性。该项目应促进与环境有关的分析测量的最新技术，并将对影响空气质量的化学过程提供更彻底的了解。此外，该奖项将使普拉瑟教授在加州大学河滨分校作为一名研究人员和教育工作者进一步推进她的整体专业发展。

This National Science Foundation Young Investigator project is in the general area of analytical chemistry, with a specific focus on the characterization of environmentally relevant aerosols. During the five-year tenure of this award, Professor Prather and her students will carry out fundamental studies on aerosol particles that are thought to participate in a number of environmentally important reactions. The size and composition of individual particles are measured using a laser-based gating system in conjunction with laser desorption and time-of-flight mass spectrometry. Particles composed of inorganic salts and polyaromatic hydrocarbons will be investigated. The goal is to identify the particle characteristics important in controlling atmospheric reactions. This project should advance the state-of-the-art of environmentally relevant analytical measurements, and will provide a more thorough understanding of chemical processes affecting air quality. Additionally, this award will enable Professor Prather to further her overall professional development as a researcher and educator at the University of California at Riverside.
