ABSTRACT:
A particle size analyzer of the sedimentation type in which a cup-shaped member is used to deposit the particles in the sedimentation fluid substantially simultaneously and at low velocity. The particles are ultrasonically dispersed as they are deposited in the fluid and are collected by a balance member which detects their receipt as a function of time. An electronic circuit connected to the balance member determines the size of the particles through the use of Stokes' Law and an empirically determined relationship between the settling velocity of the particles and their size.
