Flow field-flow fractionation: critical overview

WebField-flow fractionation (FFF) is a family of techniques, where a physical field acts perpendicular to a commonly ribbon-like channel, through which a solvent is pumped. 22,23 If the solvent viscosity is low enough, a laminar flow is generated. One method of exerting a force perpendicular to the channel is by generating a cross-flow field. how to repair an anderson window screen
