Abstract
A particle separation apparatus is disclosed. The particle separation apparatus may be for sample air stream preparation and delivery in particle detection systems. The particle separation apparatus may include a first vortex separator coupled to a second vortex separator for selecting particles in the air stream that are within a desirable size range for particle detection. The second vortex separator may further increase the concentration of particles within the desirable size range per unit volume. The particle separation apparatus may deliver the size-selected air stream to a detector, such as a laser-induced fluorescence detection system.
