Beschreibung
Zusammenfassung:	Embodiments are described for separating collecting components from a multi-component fluid such as whole blood. Some embodiments provide for controlling the amount of a component, such as platelets, introduced into a separation chamber to ensure that the density of fluid in the separation chamber does not exceed a particular value. This may provide for collecting purer components. Other embodiments may provide for determining a chamber flow rate based on a concentration of a component in the multi-component fluid, which may then be used to determine a centrifuge speed, to collect purer concentrated components.
