ABSTRACT:
A density centrifuge blood processing system comprising a separation chamber rotating about a central rotation axis, the separation chamber being coupled to an elutriation chamber, a first detector for the separation chamber to detect light from an observation region, a computational apparatus distinguishing at least two regions in the observation region and distinguishing incipient spill over of cellular components out of the elutriation chamber as a function of light intensity received from the at least two regions in the separation chamber, and a controller regulating speed of at least one pump or of the separation chamber in response to signals from the computational apparatus to avoid spill over.
