This Major Research Instrumentation (MRI) project provides for the purchase a double-focusing magnetic sector mass spectrometer to be utilized in support of research in the Department of Earth System Science and the Department of Chemistry at the University of California, Irvine. The instrument will be utilized in research addressing the atmospheric chemistry and biogeochemistry of organohalogens contributing to ozone depletion, the accumulation and origin of greenhouse gases in the atmosphere, the use of hydrocarbons as tracers of major tropospheric sources such as biomass burning, industrial emissions, and biogenic emissions, and the role of hydrocarbons in tropospheric chemistry.

本重大研究仪器（MRI）项目规定购买一台双聚焦磁扇区质谱仪，用于支持欧文市加州大学地球系统科学系和化学系的研究。 该仪器将用于研究以下问题：造成臭氧消耗的有机卤素的大气化学和地球化学;大气中温室气体的积累和来源;碳氢化合物作为主要对流层来源（如生物质燃烧、工业排放和生物源排放）的示踪剂的用途;以及碳氢化合物在对流层化学中的作用。
