Abstract

An apparatus and method for magnetic separation are provided. The apparatus and method can be used to separate magnetically linked targets from unlinked targets in a suspension. The apparatus has a two-dimensional magnetic array that includes a plurality of one-dimensional magnetic arrays that each define a Halbach array. The one-dimensional arrays are positioned adjacent to one another, and the magnetic fields defined by the plurality of one-dimensional arrays are oriented in the same direction across the array surface. A housing can support the plurality of magnetic elements of the two-dimensional magnetic array. The housing defines a container receiving surface on which a container is receivable adjacent the surface of the magnetic array. A container with a plurality of magnetically linked targets and unlinked targets may be positioned in proximity to the array surface to separate the magnetically linked targets from unlinked targets in the suspension.
