Computer operated material processing systems and method

摘要

Improvements in computer controlled material processing are disclosed including an apparatus and method in which the centrifugation of a liquid mixture in order to separate out components of the mixture with different sedimentation rates is adaptively controlled by monitoring the sedimentation of detectable particles and controlling the centrifugation so as to effect a desired localization of the detectable particles. Such adaptive control may be performed with a continuous flow centrifugal separator or a batch-type centrifuge. The detectable particles may be test particles having a sedimentation constant approximately equal to a component of interest in the mixture whose localization is desired.
