Title: Deployment of a novel aerosol mobility/mass spectrometer for quantitative chemical analysis of organic aerosols from mobile sources

Principal Investigator / Author(s): Phares, Denis J.

Contractor: University of Southern California

Contract Number: 06-330


Research Program Area: Atmospheric Processes

Topic Areas: Chemistry & Reactivity, Field Studies, Mobile Sources & Fuels


Abstract:

This project focuses on the development and deployment of novel instrumentation aimed at identifying the organic compounds that comprise the aerosol in an urban environment. Sampling locations were selected to focus on the contribution for mobile source within the Los Angeles basin. The instrument is based on a novel real-time analysis technique that employs thermal desorption chemical ionization mobility/mass spectrometry of aerosols. Since such instrumentation is never been previously reported within the scientific community, the project itself is heavily oriented towards instrumentation development and optimization. Results were obtained from extensive laboratory optimization and characterization, as well as field deployments in Pasadena and downtown Los Angeles.
