Cell Separation by Gradient Centrifugation -

1974-1-1  In this field cell separation by centrifugation began with " packed-cell" techniques which involved prolonging centrifugation beyond the point where all the cells pelletted. Stratification of the different cell types in the pellet occurred, with reticulocytes and white cells at the top of the packed cell

2010-4-15  The concept of separation efficiency, the deviation from ideal capacity, due to the simplicity of the mathematical model for the Σ value is defined. The considerations when selecting type and size of centrifuge for a given process are described, as well as the evaluation and enhancement of separability of the given process stream.
