Abstract
Particle size distribution measuring equipment includes a flow cell that can be illuminated with light so that suspended particles can scatter the light and thereby measure both particle size and frequency. A dispenser unit is connected to the flow cell for delivering a sample. A fractionator unit can pretreat the sample to provide particles over a predetermined size in a sealed chamber resulting from the impact of compressed air. The fractionated sample can be delivered to the dispenser, and a controller can automatically coordinate the preparation of the dispenser unit, the flow cell, the measuring of scattered light, and the release of the fractionated sample from the sealed chamber.
