ABSTRACT:
The mass center of a field flow fractionation channel is adjusted to coincide with the geometric center of the channel. Under these conditions, above critical rotor speeds, the mass center will coincide with the geometric center of the channel and both will coincide with the spin axis of the rotor. This ensures that all portions of the field flow fractionation channel are subjected to about the same centrifugal force.
