ABSTRACT:
Particles suspended in a fluid carrier are differentially separated by, first, grading the particles into fractions of equal settling rates and, second, separating the equal-settling particles of each fraction according to the magnetic susceptibilities of the particles. The particulate sample to be separated is passed through a two-path parallel flow system. In one path, the sample is selectively graded, by elutriation, into equal-settling fractions. Each such fraction then flows directly to the second path, where it crosses a magnetic field at a velocity proportional to its settling rate. Such proportionality between settling rate and flow velocity provides a residence time which ensures that the degree of deflection, in response to gravitational and magnetic forces, required for separate recovery of magnetic particles, on the one hand, and non-magnetic particles, on the other hand, will be attained within the active length of the magnetic field. Provision is made for simultaneous adjustment of the flow rates in the respective paths, thereby allowing selection among fractions of different settling rates while, at the same time, maintaining the desired flow rate proportionality between the two paths. The flow rates are also independently adjustable to provide for other flow requirements within the individual flow paths.
