Wikipedia

  1. Field flow fractionation

    Field-flow fractionation, abbreviated FFF, is a separation technique which does not have a stationary phase. It is similar to liquid chromatography as it works on dilute solutions or suspensions of the solute. Separation is achieved by applying a field (hydraulic, centrifugal, thermal, electric, magnetic, gravitational, ...) perpendicular to the direction of transport of the sample which is pumped through a long and narrow channel. The field exerts a force on the sample components concentrating them towards one of the channel walls, which is called accumulation wall. The force interacts with a property of the sample on which then the separation occurs, in other words on their differing "mobilities" under the force exerted by the field. As an example, for the hydraulic, or cross-flow FFF method, the property driving separation is the translational diffusion coefficient or the hydrodynamic size. For a thermal field (heating one wall and cooling the other), it is the ratio of the thermal and the translational diffusion coefficient.
