Abstract
A concentrator for increasing the particle concentration in an aerosol flow is described. The concentrator comprises a sculptured acceleration plate with a number of slit-shaped and radially extending acceleration channels and a sculptured deceleration plate with a number of slit-shaped and radially extending deceleration plate channels. Acceleration channel exit openings are spaced from a base surface on an exit side of the acceleration plate and sculptured deceleration channel entry openings are spaced from a base surface on an entry side of the deceleration plate so that a relatively large gap is provided between the acceleration plate base surface and the deceleration plate base surface allowing a waste volume flow to be exhausted through this relatively large gap at low flow resistance. The plurality of openings comprises openings of at least two different lengths.
