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 7):
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; a mixture port in communication with the inlet end of the elongated hollow channel for injecting a mixture of first nonmagnetic particles and at least second and third magnetic particles into the elongated hollow channel, wherein the first nonmagnetic particles and the at least second and third magnetic particles have separate and distinct properties with respect to one another, the properties including at least one property selected from the group consisting of magnetic susceptibility, size, and mass; 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 includes 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 separating chamber having an inlet port in fluid communication with the outlet end of the elongated hollow channel, the separating chamber having a peripheral wall and at least first, second and third sets of receptacles defined in the peripheral wall, the first set of receptacles being farther from the outlet end of the elongated hollow channel than the second and third sets of receptacles, the third set of receptacles being closest to the outlet end of the elongated hollow channel, the second set of receptacles being between the first and third sets of receptacles, further wherein the separating chamber has an arcuate wall portion and a linear wall portion, the first set of receptacles being defined in the arcuate wall portion and the at least second and third sets of receptacles being defined in the linear wall portion, the first nonmagnetic particles being separated to flow into the first set of receptacles by the semicircular separating chamber and hydrostatic or hydrodynamic forces, the at least second and third particles being separated to flow into the at least second and third sets of receptacles primarily by magnetic repulsion diverting the particles away from the externally magnetizable wire; an externally magnetizable wire extending along a transverse axis orthogonal to the longitudinal axis, the externally magnetizable wire being positioned outside of and adjacent to the separating chamber and positioned to intersect a portion of said longitudinal axis extending outside the elongated hollow channel and the separating chamber; and at least one magnetic source for generating an external magnetic field along a lateral axis substantially orthogonal to the longitudinal axis and the transverse axis, the external magnetic field inducing a magnetic field in the externally magnetizable wire, the induced magnetic field applying a repulsive magnetic force to the at least second and third magnetic particles, the first nonmagnetic particles being separated to flow into the first set of receptacles and the at least second and third magnetic particles being separated to respectively flow into the second and third sets of receptacles due to their separate and distinct properties.
