Abstract

The first successful isopycnic focusing generated by the coupled electric and gravitational fields applied to the model bidisperse mixtures of the colloidal silica and polyaniline particles of low size ratio is described. The theoretical analysis and the experimental results show that the density gradient forming liquid should not necessarily behave as a continuum regarding the focused species. This finding confirms the original prediction which was evidenced previously by the focusing under the action of high intensity centrifugal field forces only.
