dec 15, 2016 the elemental composition of mn-mgo hybrid particles was analyzed by xps measurement. the survey spectra (0⿿1200 ev) indicate the presence of c 1s, o 1s, fe 2p and mn 2p (fig. 3(a)), which accounted for 18.72%, 54.44%, 18.43% and 8.4% in the atomic fractions, respectively. the peaks for the c 1s spectrum at 284.6 and 287.8 ev are attributed to the c c group and o c o (fig. 3(b)).

the principle of eddy current separation introduced in this article is shown in the figure below. a rotating drum wrapped by a permanent magnet ( high performance ndfeb magnets) produces a alternating magnetic field. when a metal with conductive properties passes through the magnetic field, an eddy current will be generated in the metal.

jan 01, 2017 the use of these refined magnetic sources implies stronger magnetic fields and, as a result, increases the cost of the separation process since they require increased power supply or complex cryogenic cooling systems in the case of sc separators. thus, the use of pms is preferred because of their lower operating cost and simplicity.

this article reports the purification and separation of magnetic nanoparticle mixtures using differential magnetic catch and release (dmcr). this method applies a variable magnetic flux orthogonal to the flow direction in an open tubular capillary to trap and controllably release magnetic nanoparticles. magnetic moments of 8, 12, and 17 nm diameter cofe2o4 nanoparticles are calculated using

Microfluidic separation system for magnetic beads

In this work a microfluidic separation system for magnetic beads was experimentally realized according to theoretical simulations. the manipulation of magnetic beads is achieved by magnetic gradient fields resulting from conduc-ting lines near the microfluidic channel. experi-mental and calculation results are compared with each other.

magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). a simple magnetic separation circuit can be seen in figure 1.2.5 [9].a slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.

jul 25, 2009 the magnetic field of a planet or a planetary moon contains contributions from a variety of sources in the environment of the body (external sources) and its interior (internal sources). this chapter describes different methods that have been developed for the separation of external and internal source contributions, and their application to selected planets and one of jupiter’s moons, ganymede.

a magnetic sifter is adapted for manipulation of biological cells by providing a greater pore density at the edge of the sifter than at the center. application of an external magnetic field to the sifter causes high magnetic fields and field gradients at the sifter pores. these conditions are suitable for capturing magnetically tagged or labeled cells at the sifter pores.
