摘要:
The present application discloses a process for the high throughput separation of at least one distinct biological material from a sample using magnetic tags and a magnetic separation set up capable of processing at least about 106 units/second. A magnetic field gradient is used to deflect target material bearing a magnet tag from one laminar flow stream to another so that the magnetically tagged target material exits a separation chamber via a different outlet than the rest of the sample. The process is applicable to isolating several distinct biological materials by directing each via magnetic deflection to its own unique outlet. The application also discloses a system for performing the process and a kit that includes the system and the magnetic tags.

A system and method for protecting a superconductor from a quench condition. A quench protection system is provided to protect the superconductor from damage due to a quench condition. The quench protection system comprises a voltage detector operable to detect voltage across the superconductor. The system also comprises a frequency filter coupled to the voltage detector. The frequency filter is operable to couple voltage signals to a control circuit that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system is operable to detect whether a quench condition exists in the superconductor based on the voltage signal received via the frequency filter and to initiate a protective action in response.
