Abstract
A fluid processing system that can include a sample container having a sample chamber for containing a fluid and a plurality of magnetic particles and at least one movable magnetic assembly configured to be movably inserted into or out of the sample chamber. The movable magnetic assembly can include a plurality of electromagnets that generate a magnetic field within at least a portion of the sample chamber when the assembly is inserted at least partially into the sample chamber. The fluid processing system can also include a signal generator that applies electrical signals, e.g., AC electrical signals, to the electromagnets of the magnetic assembly and a controller coupled to the signal generator that is configured to control phases of the electrical signals applied to the electromagnets to generate magnetic field gradients within the portion of the sample chamber effective to magnetically influence the plurality of the magnetic particles.
