MRI: Acquisition of an Aerosol Time-of-Flight Mass Spectrometer for Research and Undergraduate Research Training in Properties of Atmospheric Aerosol Particles

有了这个主要研究仪器（MRI）计划的奖项，卡尔顿学院化学系将获得一个气溶胶飞行时间质谱仪。这一设备将加强若干领域的研究，包括：（a）研究在卡尔顿学院地区发现的悬浮微粒的化学成分和来源;（B）探索雨水和雪冲刷造成的微粒湿沉降;（c）研究柴油发动机的排放物随各种操作参数的变化。 更深入地了解大气中的气溶胶颗粒对于了解环境和健康影响至关重要。 该项目将为卡尔顿学院的本科生提供机会，与来自威斯康星州-麦迪逊大学的本科生和研究生以及来自两个机构的高级科学家合作。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Carleton College will acquire an aerosol time-of-flight mass spectrometer. This equipment will enhance research in a number of areas including a) the study of the chemical content and source origin of aerosol particles found in the Carleton College area; b) the exploration of wet deposition of particles through both rain and snow washout; and c) the study of the emissions from diesel engines as a function of various operating parameters. A deeper understanding of aerosol particles in the atmosphere is crucial to understanding the environment and health effects. This project will provide opportunities for Carleton College undergraduates, in collaboration with undergraduates and graduate students from the University of Wisconsin - Madison, and senior scientists from both institutions to work together.
