Abstract

A single-stage impactor device, capable of fractionating a bacterial aerosol into its component mass size classes while preserving the viability of sensitive vegetative cells against the deleterious effects of desiccation and impaction, is described. Among the valuable features of the impactor are its negligible wall loss, ease of fabrication and use, and relative inexpensiveness.
