· This paper focuses on a separation device allowing completely continuous separation. Technically, based on a continuous separation device, all steps including adsorption, elution and washing steps can be performed continuously. A promising approach to HGMS is a hybrid process, combining magnetic separation with centrifugation.
· Here, an efficient continuous separation mechanism is devised by the use of an external magnetic field and the weak mag- netization of MOFe 2O 3at the working temperatures. The mechanism is suitable for systems of ferrites with a Curie temperature in the range 500–800 C where water or CO 2 decomposition occurs.

· Magnetic separation of cells is advantageous over the conventional methods mainly because it lets target cells to be isolated directly from the medium, i.e. blood, bone marrow, tissue homogenates, stool, cultivation, media, food, water, soil etc. ( Melville et al., 1975; Safarik and Safarikova, 1999 ).
The current research and development initiatives and needs in magnetic separation, shown in Fig. 7, reveal several important trends.Magnetic separation techniques that have been, to a greater extent, conceived empirically and applied in practice, such as superconducting separation, small-particle eddy-current separation, and biomedical separation, are being studied from a more …

We first characterized the interplay between the droplet velocity and the strength of the magnetic field and its effect on marginalization. We found that marginalization is optimal at the midline of the magnet and that marginalization is a good predictor of bead enrichment through splitting at low to moderate droplet velocities.

Magnetic separation is a method to separate and capture fine magnetic particles by the magnetic force acting on the particles in a gradient magnetic field. For the practical use of the magnetic separation, it is necessary to remove the captured particles from the separation area where the magnetic force is active. High gradient magnetic separation utilizes the high spatial magnetic …
