ABSTRACT:
An impactor apparatus operable to collect particles for subsequent gravimetric or chemical analysis. The apparatus has a first assembly for supporting particle impaction means and a second nozzle assembly releasably mounted on the first assembly having nozzle means for directing gas and particles to the particle impaction means. The nozzle assembly can be removed from the first assembly supporting the particle impaction means and reassembled after an impaction test on a new assembly having cleaned particle impaction means. A cover is mounted on the assembly so that the assembly, along with the particle impaction means, can be transported to the laboratory for analysis. A modification of the particle impactor apparatus has rotating table means aligned with a plurality of nozzles so that a uniform layer of particles are deposited on each of the impaction plates carried by the tables. A plurality of rotating tables are employed in series with separate nozzle means to provide a cascade inertial impactor apparatus.
