A method, system, apparatus, and article of manufacture provide a cross-flow migration classifier capable of separating particles. The classifier provides a channel through which a sample, having one or more particles, passes in a first direction, wherein the channel comprises two or more walls that are permeable to a flow of fluid. A cross-flow enters the channel through one of the permeable walls and exits through another of the permeable walls. An imposed field is applied in a second direction that is counter to the cross-flow and having an orthogonal component to the first direction. The imposed field causes one or more of the particles to migrate at a first velocity opposite and/or equal to a second velocity of the cross-flow. The particles that migrate opposite to the cross-flow are continuously discharged from the cross-flow migration classifier.
