We describe the development and performance evaluation of a system for optical interrogation, subsequent selection, and collection of individual aerosol particles entrained in an inlet air stream. Elastic scatter and laser-induced fluorescence obtained from single particles on-the-fly provide compositional information for classification criteria. Individual particles could then be selectively electrically charged and captured to a conductive substrate with an electric potential. The optical subsystem also includes a novel two-beam velocimeter to provide accurate downstream timing. Good overall quantitative performance values are reported for particles in the size range of 1 8 μm at mean rates up to 4 kHz .
