Abstract
A rigorous analysis of the phenomenon of field-flow fractionation (FFF) is presented for particles which are both nonspherical in shape and of sufficient size (compared with apparatus dimensions) to be significantly influenced by wall effects. Calculations are presented for axially-symmetric particles in an arbitrary flow field. Orienting torques directed along the symmetry axis of the particle are also considered. The theory is compared with the experimental data of Berg, Purcell, and Stewart. Reasonably satisfactory agreement is observed.Keywords
