Apparatus and method for collection, sorting, concentrating and impinging particles on a surface

摘要

The present invention is drawn to an apparatus and method for collection, sorting, concentrating and impinging particles on a surface, primarily for use in detecting and classifying chemicals, particles, vira, and bacteria in fluids. In addition to mechanical and aerodynamic filtering, the present invention uses isokinetic filtering to acquire particles of interest by creating a local vortex in the fluid through use of a dam element at a high angle of attack. This isokinetically sorts particles by density and aerodynamic diameter.
