Revision of the calibration experiment in asymmetrical flow field-flow fractionation

Journal of Chromatography A, 2021
Asymmetrical flow field-flow fractionation is a versatile chromatographic fractionation method. In combination with at least one detection technique it is used for size-based separation of colloids, biomolecules and polymers. Although often used as pure separation method, a well-elaborated theory is available that allows precise quantification of the ...

Asymmetric flow field flow fractionation methods for virus purification [PDF]

Journal of Chromatography A, 2016
Detailed biochemical and biophysical characterization of viruses requires viral preparations of high quantity and purity. The optimization of virus production and purification is an essential, but laborious and time-consuming process. Asymmetric flow field flow fractionation (AF4) is an attractive alternative method for virus purification because it is

Characterization of red wine native colloids by asymmetrical flow field-flow fractionation with online multidetection

, 2021
Colloids are an important component of wines, but their study is challenging due to their instability. Asymmetrical Flow-Field Flow Fractionation (AF4)-multidetection is here proposed as a suitable approach to isolate and characterize red wine colloids ...
