2.4 High-Gradient Magnetic Separator (HGMS) As its name implies, a high gradient magnetic separator employs magnetic field charges to separate magnetic materials. Marston and Kolm introduced this method at the Massachusetts Institute of Technology in the late 1960s and early 1970s.

Magnetic separation plays an increasingly important role in analytical chemistry, nanotechnology, biochemistry, and molecular biology research …

2.1 Introduction. The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three main categories, namely diamagnetic, paramagnetic, and ferromagnetic.

Alternatively, these coated microspheres were utilized for extracting PSP toxins from naturally contaminated mussel samples; it was shown that magnetic separation could be a convenient alternative to conventional extraction procedures used in toxin purification prior to sample analysis (Devlin et al. 2011a).
