A system for plasma reduced blood component collection during blood processing comprises: a venous access device (24), a blood component separation device (12), a return line (27) and a reintroduction line (40). The venous access device is provided for drawing a first volume of whole blood from a subject and returning blood components to the subject. the blood component separation device is provided for separating the drawn blood into a first blood component and a second blood component, the blood component separation device configured to send the first blood component to a first blood component bag (18) using a surge elutriation method. The return line fluidly connects the venous-access device and the blood component separation device for returning the second blood component to the subject. The reintroduction line fluidly connects the first blood component bag and the blood component separation device. The first blood component within the first blood component bag is reintroduced into the blood component separation device when a second volume of whole blood is withdrawn from the subject, thereby creating an enlarged layer of the first blood component within the blood component separation device. The enlarged layer of first blood component is removed from the blood component separation device using a surge elutriation method.
