Abstract
A density centrifuge blood processing system comprising a separation chamber rotating about a central rotation axis, the separation chamber having an outflow passage, a light source in optical communication with the density centrifuge blood processing system, the light source providing an incident light beam for illuminating an observation region and a viewing region on the outflow passage, a first detector for the separation chamber to detect light from the observation region, a second detector for the outflow passage, a computational apparatus distinguishing one or more phase boundaries in the observation region and distinguishing fluid composition in the viewing region as a function of light intensity received from the viewing region, and a controller regulating speed of at least one pump or of said separation chamber in response to signals from the computational apparatus.
