Abstract
Magnetic Particle Imaging (MPI) requires high-performing tracer materials that are highly magnetic monodispersed particles with fast remagnetization behaviour. Known separation techniques only allow for fractionation of magnetic particles based on differences in magnetic volume. Proposed is a separation method, which allows for separation of magnetic particles with respect to their dynamic response onto an oscillating high gradient magnetic field.

Method for separating magnetic particles (1), wherein the particles are circulated at least once through at least one separator column (11) with a matrix (12), the method comprising:
- a size selection step, wherein the particles (1) are selected according to their size,
- an AC fractionating step, wherein the particles (1) in the separator column (11) are subjected to a high gradient oscillating magnetic field (30).
Separator column (11) for use in a separator system (10), the separator column comprising a tube (13) and a matrix (12), the matrix being adapted to capture at least one component of a mixture of magnetic particles (1) as the mixture is circulated through the tube (13), wherein the matrix (12) comprises a soft magnetic material.
