An aerosol concentrator using the virtual impaction principle has been designed, fabricated, and evaluated. Particles larger than a designed cutoff aerodynamic diameter are enriched in a bleed flow that is 5%-40% of total flow, and up to 95% of vapors, gases, or small particles in the original aerosol are extracted. The device has been used in conjunction with compressed air nebulizers to produce enriched aerosols of PuO2, polystyrene, and other particulates while removing excess water vapor or gases such as SO2 and NH3.
