A single-stage disposable channel and seal that provides for leukocyte and granulocyte collection by continuous-flow cell separation (CFCS) has been designed by the IBM Corporation. This paper describes (1) the separation characteristics of whole blood as it responds to varying gravitational (G) forces and flow rates through the channel; (2) the mechanism by which the buffy coat accumulates and is extracted; (3) the efficiency of extraction; (4) those donor and procedural variables that contribute to the final yield; (5) posttransfusion increment response in patients; and (6) the functional integrity of the cells collected.
