Magnetic design considerations for devices and particles used for biological high-gradient magnetic separation (HGMS) systems

An overview of the magnetic systems used in biological high-gradient magnetic separation (HGMS) is presented. The magnetic design parameters of a range of separation devices are discussed. Such designs have distinct magnetic field characteristics and are usually tailored to meet the needs of particular protocols. The various types of magnets and particles are also discussed, with a comparison of materials available and their magnetic properties
