Application of Chemical Ionization Mass Spectrometry for Atmospheric Sciences: Measurement of Volatile Organic Compounds Emitted from Western US Wildfires
Volatile organic compounds (VOCs) in the troposphere are emitted from a wide variety of natural and man-made sources and resulting in environmental issues such as air pollution and climate change. Chemical ionization mass spectrometry (CI-MS) techniques using specific reagent ions such as H3O+ 1) and NO+ 2) allow real-time measurements of various VOCs in air with high sensitivity and fast time response. Modern CI-MS equipped with time-of-flight (ToF) mass analyzers can measure hundreds of compounds simultaneously. The applications of CI-MS have greatly promoted understanding VOC sources and their roles in environmental issues, and therefore, CI-MS has become a well-established analytical technique for in situ VOC measurements in atmospheric sciences. In this presentation, recent applications of CI-MS for atmospheric science are presented, using following examples from research in biomass burning emissions and chemistry.
