Definition
Flow field-flow fractionation in which the speed of mobile phase is constant along the length of the channel due to constant channel width.

Notes
1) The width is constant except for triangular sections at each of the ends of the channel.
2) Theory and data analysis are simplified by the assumption of constant flow.
