Outline of Final Research Achievements

Understanding the behavior of various organic acids and resulting aerosols in the atmosphere is one of important topics in atmospheric chemistry. However, a methodology for high-sensitive and real-time measurements of organic acids in aerosol phase has not been established yet. On the basis of these backgrounds, the following subjects were conducted in this work: (i) development of real-time vaporization system for atmospheric aerosols using high-temperature plasma jet, (ii) development of a methodology for comprehensive quantitation of atmospheric volatile organic compounds using proton-transfer-reaction mass spectrometry, and (iii) chemical characteristics of volatile organic compound emission from western US wildfire fuels.
