Title:
DEVICE FOR DISTINGUISHING DYNAMIC MOBILITY OF AEROSOL PARTICLES
Document Type and Number:
Japanese Patent JPH09269288
Kind Code:
A
Abstract:
To provide a compact dynamic mobility distingushing device which may be used as a generator for generating monodispersed aerosol for ultra fine particles.
A device comprises two discs 30,32 which are placed in parallel to each other with a distance to define a dynamic distingushing region 31, and an upper disc 30 comprises an annular slit having a radius r1 and a central suction port 38 for letting a laminar, centripetal, stable air current flow into the dynamic selection region. In a lower disc 32 is provided an annular hole 36 having a mean radius r2 smaller than the radius r1.
