Apparatus for sampling and characterizing aerosols

Patent ·
OSTI ID:6064829
This patent describes an apparatus for sampling aerosols which consists of: a chamber having an inlet at one end and an outlet at the other end. The chamber includes: vertically stacked, successive particle collection stages located within the chamber between the chamber inlet and chamber outlet and together with the chamber, this defines a flow path from the chamber inlet, through successive collection stages, to the chamber outlet. Each of the collection stages includes: a separator plate located within and extending across the chamber for separating that stage from the previous stage. The separator plate has an inlet opening extending through it; and a channel guide, mounted transverse to the separator plate, defining a labyrinthine flow path from the inlet opening to the inlet opening of the next stage, and particle collectors supported by the channel guide and located within the labyrinthine flow path; the particle collector within the collection stage of the chamber includes a combination of collector plates for gravity separation, fine wire impactors, and diffusion battery screens.
