Abstract
Particles are dispensed under controlled conditions to achieve an accurate number of particles by passing a suspension of the particles through a particle detecting device, obtaining a cumulative particle count, comparing the cumulative particle count with a target value, and shutting off the suspension flow once the particle count reaches the target value, all performed by automated means.
