An apparatus and method are provided for separating components of a fluid or particles. A separation vessel having a barrier dam is provided to initially separate an intermediate density components of a fluid, and a fluid chamber is provided to further separate these intermediate density components by forming an elutriative field or saturated fluidized particle bed. The separation vessel includes a shield for limiting flow into the fluid chamber of relatively high density substances, such as red blood cells. The separation vessel also includes a trap dam with a smooth, gradually sloped downstream section for reducing mixing of substances. Structure is also provided for adding additional plasma to platelets and plasma flowing from the fluid chamber. The system reduces clumping of platelets by limiting contact between the platelets and walls of the separation vessel.
