Abstract:
The magnetic particle separator uses an induced magnetic field to separate magnetic particles held in solution by magnetophoresis. The magnetic particles may be, for example, inherently paramagnetic or superparamagnetic, may be magnetically tagged or the like. First and second magnetic particles initially flow along a longitudinal direction. An external magnetic field along a lateral direction, orthogonal (or near orthogonal) to the longitudinal direction, is applied to an externally magnetizable wire, which extends along a transverse direction orthogonal to both the longitudinal and lateral directions. The external magnetic field generates an induced magnetic field in the externally magnetizable wire, and the induced magnetic field generates repulsive magnetic force on the first and second magnetic particles. Due to differing magnetic susceptibility, size and/or mass between the first and second magnetic particles, they are separated by following separate paths generated by the respective magnetic forces thereon.

Claim (Index 1):
A magnetic particle separator, comprising:\n an elongated hollow channel extending along a longitudinal axis, the elongated hollow channel having opposed inlet and outlet ends and defining an unencumbered interior expanse; a mixture port in communication with the inlet end of the elongated hollow channel for injecting a mixture of at least first, second and third magnetic particles into the elongated hollow channel, wherein the at least first, second and third magnetic particles have separate and distinct properties with respect to one another, the properties being selected from the group consisting of magnetic susceptibility, size, mass and a combination thereof; a buffer port in communication with the inlet end of the elongated hollow channel for injecting a buffer solution into the elongated hollow channel, such that the mixture of the at least first, second and third magnetic particles in the buffer solution flow unencumbered and completely through the elongated hollow channel along the longitudinal direction toward the outlet end thereof, wherein the buffer port comprises first and second branches positioned symmetrically about the mixture port, such that flow of the buffer solution from both of the first and second branches hydraulically focuses flow of the mixture of the at least first, second and third magnetic particles in the buffer solution through the elongated hollow channel; a magnetic particle separator chamber located at the outlet end of the hollow channel, the magnetic particle separator including:\n a first outlet channel disposed at the terminus of the outlet end of the elongated hollow channel; \n a second outlet channel disposed adjacent the first outlet channel at the outlet end of the elongated hollow channel; \n a third outlet channel disposed adjacent the second outlet channel at the outlet end of the elongated hollow channel, the first, second and third outlet channels being in communication with each other at a junction therebetween within the magnetic separator chamber; \n an externally magnetizable wire extending along a transverse axis orthogonal to the longitudinal axis, the externally magnetizable wire being positioned solely contiguous to the first outlet channel; and at least one magnetic source for generating an external magnetic field along a lateral axis substantially orthogonal to both the longitudinal axis and the transverse axis, the external magnetic field generating an induced magnetic field in the externally magnetizable wire, the induced magnetic field applying a repulsive magnetic force to the at least first, second and third magnetic particles, the at least first, second and third magnetic particles being separated to flow into the first, second and third outlet channels due to their separate and distinct properties.
