FFF is an elution technique, like chromatography, and the experimental sequence of pump, column, detector, and Asymmetrical flow field-flow fractionation system parameters Per Jungnelius and its use on optimized quantitative antibody separation Uppsala Universitet 4/58 Executive Summary The new analysis technique Asymmetrical Flow Field-Flow Fractionation, A4F, has the potential to transform the field of protein aggregation analysis. Field-flow fractionation, abbreviated FFF, is a separation technique where a field is applied to a fluid suspensionor solutionpumped through a long and narrow channel, perpendicular to the direction of flow, to cause separation of the particles present in the fluid, depending on their differing "mobilities" under the force exerted by the field. The asymmetric flow Field-Flow Fractionation (AsFlFFF) system, is coupled with photodiode array UV/Vis detector, fluorescence detector and refractive index detectors (two mass detectors), and multiangle static and dynamic light scattering detectors.
