ABSTRACT:
The invention relates generally to methods of monitoring and controlling the processing of blood and blood samples, particularly the separation of blood and blood samples into its components with a two-dimensional optical measurement and control device. The method may comprise the steps of providing a blood processing system comprising a density centrifuge blood processing system and an elutriation blood processing system; filling the elutriation blood processing system with a desired component; measuring a cellular flux of cells entering the elutriation blood processing system with a two-dimensional optical control system; and flushing the elutriation blood processing system.
