The invention provides a micro scaled method and system for separating a subgroup of cells and/or particles from a mixture of different types of cells and/or particles in a suspension. The suspension is forced under pressure into an inlet and further into a pre-alignment channel wherein the suspension is subjected to a two dimensional acoustic force directed perpendicular to the length direction of the pre-alignment channel. The suspension is then forced into a second inlet and further into at least one separation channel wherein the mixture of cells and/or particles are forced towards the walls of the channel and subjected to a one dimensional acoustic force directed perpendicular to the length direction of the separation channel. Cells and/or particles having the same size and/or mass density and/or compressibility are collected through at least two outlets.
