Annotation
Force field programming in gravitational field-flow fractionation based on modulation of hydrodynamic lift forces has been introduced. The flow-rate control of activity of hydrodynamic lift forces has been accomplished by either programmable pump or non-constant cross-section of the fractionation channel. Several flow-rate gradients induced by programmed pumping (step gradients, linear gradients, parabolic, and combined ones) or by the changing profile of the fractionation channel (channels with non-constant height or width) have been used for separation of a model mixture of silica gel particles.
