Analytical study on open gradient magnetic separation using quadrupole magnetic field

Separation characteristics of the open gradient magnetic separation using the quadrupole magnetic field was numerically evaluated. A numerical model to analyze the diffusion process of the magnetic particles suspended in the fluid in the quadrupole magnetic field was developed based on the equation of the mass conservation. The concentration profiles of the magnetic particle are numerically obtained by using the model. The feasibility of the open gradient magnetic separation using the quadrupole magnetic field was verified by the numerical results.
