ABSTRACT:
A sampling device for separating particles entrained in a gaseous medium including a plurality of plates spaced from each other a prescribed distance with each of the plates defining a plurality of jet impaction apertures therethrough with the apertures of each plate staggered with respect to the apertures of the plates adjacent thereto so that the entrained particles will be separated by jet impaction by each plate on the next downstream plate, a collection substrate carried by the upstream side of each of the plates onto which the particles are impacted and defining a plurality of slots therethrough adapted to overlie the apertures through the plates on which the collection member is carried with means for maintaining a prescribed spacing between the collection substrate and the adjacent upstream plate and for dividing the flow of the gaseous medium through the plates into sub-flow paths.
