Abstract :
This paper presents numerical simulation results for characteristics of separating multiple kinds of magnetic particles with different magnetic susceptibility by magnetic chromatography using quadrupole magnetic field. The dependencies of separation of two kinds of particles with different magnetic susceptibility on the system parameters are evaluated by the model to analyze the transient particle transport process developed in our previous study. The calculated time evolutions of the particle concentration in the narrow cylindrical channel placed in the quadrupole magnetic field show the flow velocity difference of the particle transport corresponding to the difference of the magnetic susceptibility. The numerical results also show that the separation of paramagnetic particles of 50nm is possible
