Hydrodynamic radius determination with asymmetrical flow field-flow fractionation using decaying cross-flows. Part 1. A theoretical approach.
Direct determination of hydrodynamic radius from retention time is an advantage of the field-flow fractionation techniques. However, this is not always completely straight forward since non-idealities exist and assumptions have been made in deriving the retention equations. In this study we investigate the effect on accuracy from two factors: (1) level of sophistication of the equations used to de
