Effects of Elevated Pressure on Gas Phase Ionic Reactions

本项目属于分析化学和表面化学的一般领域以及气相离子化学和质谱的子领域。在这项为期三年的持续资助期间，Grimsrud教授和他的同事将进行一系列研究，旨在阐明在接近一个大气压的压力下控制复杂离子-离子和离子-分子反应的基本动力学和平衡过程。该项目的目标是探索在这种压力下操作的仪器的分析效用。本项目目标的成功实现将为合理设计和优化利用在重大压力下运行的分析仪器提供实质性框架，特别是那些对快速可靠地表征环境重要痕量物种至关重要的分析仪器。

This project is in the general area of analytical and surface chemistry and in the subfields of gas phase ion chemistry and mass spectrometry. During the tenure of this three-year continuing grant, Professor Grimsrud and his co-workers will conduct a series of investigations aimed at elucidating the fundamental kinetic and equilibrium processes governing complex ion-ion and ion-molecule reactions at pressures approaching one atmosphere. The goal of this project is to explore the analytical utility of instruments that operate in this pressure regime. %%% The successful attainment of the goals of this project will provide a substantive framework for the rational design and optimal utilization of analytical instruments that operate at significant pressures, particularly those essential to the rapid and reliable characterization of environmentally important trace species.
