Ion Mobility Analysis of Gaseous and Particulate Pollutants

ANTHONY S. WEXLERDepartment of Mechanical and Aeronautical EngineeringDepartment of Civil and Environmental EngineeringDepartment of Land, Air and Water ResourcesUniversity of California, DavisAbstract:USC faculty, staff and students have played a leading roll internationally in elucidating the physical and chemical constituents in the atmosphere and the health effects that they elicit. But like investigators everywhere, this work has been limited by the spatial resolution of the instruments that are available. Usually, a few measurements in a vast urban area such as Los Angeles must suffice due to instrument costs even though there are tremendous spatial inhomogeneities for many of the toxic pollutants. This talk will present a nascent effort at UC Davis to design and build an inexpensive, easily manufactured ion mobility spectrometer that is suitable for analyzing many common pollutants, especially the organic ones.
