Abstract
79160 Organic matter is a major constituent of airborne particles, comprising 20-50% of the PM2.5 mass in many regions; yet, its characterization is difficult. Especially important is the real-time characterization of organic matter at the molecular level. To better understand the effects of organic matter on climate, and to understand sources of these aerosols, better characterization methods are needed. This project will develop an in situ instrument that would dramatically improve our ability to separate, identify, and quantify individual organic compounds. The instrument will utilize multidimensional chromatography and time-of-flight mass spectrometry coupled to an aerosol collection and thermal desorption system. Phase I will test the interface of the aerosol collection system with multidimensional chromatography, using both known standard aerosols and ambient aerosols. Analyses will be done by flame ionization detection. Commercial Applications and Other Benefits as described by the awardee: Commercial applications include the monitoring of atmospheric aerosols for elucidating the role of organic matter on the global radiation balance for climate research, and for understanding the sources of organic matter for developing air pollution control strategies.
