ABSTRACT:
A method and apparatus for flow field-flow fractionation involving the application of a lateral cross flow superimposed on a channel fluid flow in a field-flow fractionation system. The cross flow is developed by applying a pressure across semipermeable plates which substantially define a narrow channel region carrying a fluid substance to be subjected to the influence of the cross flow. This cross flow causes differential migration of solute material carried by the channel flow, thereby providing application to numerous processes such as separations, fractionation, solute exchange, purification, dialysis and ultrafiltration.
