Flow field-flow fractionation
WebAsymmetrical flow field-flow fractionation is a well established method for sizing and quantifying different aggregate species in protein formulations. A major advantage of AF4 is the use of the formulation buffer of the protein as the mobile phase. Read Application Note. WebField-flow fractionation (FFF) is a unique method for separating macromolecules and nanoparticles by size. The power of FFF resides in its essential tunability: simply by changing flow rates, a single separation channel can be used to explore complex samples comprising molecules, particles and emulsions across the entire size range, with superb …

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, ...) … See more FFF is applicable in the sub-micron range (from 1 nm to several microns) in the "normal" mode or up to 50 microns in the so-called steric mode. The transition from normal to steric mode takes place when diffusion becomes … See more FFF does not work for small molecules, because of their fast diffusion. For an effective separation, the sample has to be concentrated very close to the accumulation wall (a distance less than 10 µm), which requires the drift velocity caused by the force … See more Separation in Field flow fractionation takes place in a channel. It is composed of a top and bottom block which are separated by a spacer. The spacer has a cut-out (rectangular or … See more Most techniques available today are advances on those originally created by Prof. Giddings nearly 4 decades ago. Symmetrical flow Of these … See more FFF offers a physical separation of complex and inhomogeneous samples, which potentially cannot be characterized by other separation methods like Size-exclusion chromatography See more FFF was devised and first published by J. Calvin Giddings in 1966 and in 1976 he published on Flow-FFF which is the most important FFF … See more In FFF the display of detector signals as a function of time is called fractogram, in contrast to the chromatogram of column chromatography … See more WebStudying FFF theory.
