Title: An In-Situ Instrument to Assess the Concentration and Phase Partitioning of Atmospheric Semi-Volatile Organic Compounds
Agency: DOE
Contract: DE-FG02-08ER86335
Award Amount: $100,000.00


Semivolatile organic matter is pervasive in the atmosphere. Its effect on the radiation balance of the earth depends on how this material is partitioned between the vapor and particle phases. Yet, no currently available instrumentation provides simultaneous, quantitative measurement of semivolatile organic vapor and particle phases at the molecular level. Previous work involved the development of the Thermal Desorption Aerosol Gas Chromatography Mass Spectrometer, TAG BK10, which provides identification and quantification of organic constituents in atmospheric particles at the molecular level with hourly measurements. In this project, the collection and desorption system of the TAG will be modified to provide quantitative data on the concentration and phase partitioning of semivolatile organic species at the molecular level. Commercial Applications and other Benefits as described by the awardee: Identification of the constituents of semi BK29BK15volatile organic matter at the molecular level, along with the assessment of its phase partitioning in the atmosphere, is critical for elucidating transformation and formation processes, assessing affects on global climate, and identifying sources. The technology should contribute to the monitoring of parameters important to global climate change and air pollution
