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


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.
