Bruker BioSpin sets record with 950 MHz magnet

Bruker BioSpin has launched the world's highest field actively shielded NMR magnet at 950 MHz, which allows higher sensitivity and unrivalled spectral dispersion whilst maintaining same size cryostat and identical cryogenic performance as the 900 US2.

With the launch of the 950 MHz superconducting magnet, Bruker breaks its own previous world record for actively-shielded NMR magnets established two years ago with the introduction of the 900 US2.

More importantly, Bruker have managed the upgrade with the difference in price between the 950 US2 and the 900 US2 set at $1.95m (€1.5m)

"The new 950 US2 will further improve ultra-high field NMR performance, with very reasonable siting costs and enhanced siting flexibility in labs with multiple NMR systems," said Gerhard Roth, managing director of >Bruker BioSpin's Magnet Division.

"Moreover, our 950 US2 features enhanced suppression of external field disturbances, further improving the stability and overall NMR performance in challenging environments."

The 950 US2, improves on its predecessor by combining Bruker BioSpin's UltraShield active-shielding and UltraStabilized sub-cooling technologies.

The full line of Bruker BioSpin CryoProbes is compatible with this new 950 US2, enabling users to benefit from the increased sensitivity of the cryogenically cooled probes.

The 950 US2 features the same 5 Gauss stray field as the 900 US2, making it very convenient to site due to its relatively small footprint.

The complete Avance II NMR system with the 950 US2 magnet occupies an overall footprint of less than 600 square feet, compared to the 3,600 square feet of lab space that is required for an unshielded 950 MHz magnet.

The most outstanding feature of a superconducting magnet is its ability to support a very high current density with asmall resistance. This characteristic permits magnets to be constructed that generate intense magnetic fields with little or no electrical power input.

This feature also permits steep magnetic field gradients to be generated at fields so intense that the use of ferromagnetic materials for field shaping is limited in effectiveness.
