A method for separation of solutes in an aqueous sample, comprising the steps of: (a) imposing an electrical potential gradient radially through a rotatable annulus comprised of an adsorbent material, said annulus having a first and a second end; then (b) introducing, at a predetermined point at said first end of said annulus, a fluid sample comprising at least one separable constituent while continuously rotating said annulus, such that said predetermined point is stationary relative to the rotating annulus; and thereafter (c) eluting said sample from said second end of said annulus such that said constituent is collected at said second end at a radial position which is determined as a function of rf, qe and wqf=distance of said predetermined point from the center of said annulus; Ve=electrophoretic mobility of said constituent in said adsorbent material; and w
