ABSTRACT

The environmental aerosols used were those found in typical motor vehicle exhaust and cigarette smoke. Several environmentally relevant issues associated with the inherent capacity of multiphoton ionization fast conductance (MPI-FC) to be applicable to on-line study of the aerosol aqueous dissociation status were specifically addressed. The substantial influence of aerosols on the environment is recognized and appreciated. Individual particle analysis of airborne pollutants provides important insights into the source, formation, and environmental impact. Charged particle mobility measuring analytical approaches could be roughly classified according to their environmentally relevant applications to pollution screening and monitoring. The liquid droplet sampling is especially promising for on-line aerosol analysis, although other sampling techniques are relevant to environmental applications. For the ambient condition operational MPI-FC facility, an ever-increasing amount of ambient air aerosols should be accommodated by the microdroplets anyway. These would act upon the incoming photo flux as the light-scattering matrix.
