Magnetic Separation Systems
Cryomagnetics laboratory-scale magnetic separation systems combine 5–15 Tesla superconducting magnets with 7.8 cm vertical room-temperature bores, robust cryostats designed to resist quench under matrix removal, and configurations from standard low-loss dewars to fully cryogen-free cryocooler-cooled platforms.
Cryomagnetics has been a pioneer in superconducting magnet systems for years – both in magnets for separation as well as research.
Cryomagnetics' facility in Oak Ridge, Tennessee is fully equipped to manufacture superconducting magnets, dewars, and related instrumentation.
Cryomagnetics has built many superconducting magnet systems used for magnetic separation. In fact, it is possible you are using a Cryomagnetics' system without knowing it!
As a leader in high-field superconducting magnet technology, Cryomagnetics has the experience and capability to manufacture high field magnetic separation systems.
Typical superconducting magnet–based laboratory systems of the past operate at 5 to 6 Tesla. Cryomagnetics' 9 Tesla system is the premiere system for testing and analysis of today.
Laboratory-Scale Systems
Superconducting magnets suitable for this application usually range in 5 – 9 Tesla average field intensities. Higher fields are possible.
To maximize the effective area of magnetic separation, central field homogeneity is typically +/- 10% over at least a 25cm length. The superconducting magnet is designed for a fast charge and discharge rate so time between back flushes is minimized.
Bore sizes typically are between 5cm and 12.5cm. Systems are designed and built such that if the matrix is removed from the magnetic field while the superconducting magnet is energized, the system will be able to withstand the forces generated by the moving matrix without quenching.
It is common to have a maintenance free refrigerator system installed on the cryostat to maintain low liquid helium consumption and to minimize cryogen refill procedures. Using a closed-cycle refrigerator configuration eliminates the need for liquid nitrogen and thereby significantly reduces the maintenance requirements of the cryostat. Cryostats with this type configuration usually have a liquid helium hold time of at least 90 days while in static mode. The system pictured is a 9T system with this configuration.
Systems are available that do not require liquid cryogens at all. The superconducting magnet is cooled by an efficient cryocooler. Both air-cooled and water-cooled compressors are available. Please contact the factory for information on systems not listed.
