Developed to address the scientific requirements for increased sensitivity and higher resolution in order to study larger proteins, functional disorder and macromolecular complexes, Bruker has successfully energized the world's first stable and homogeneous standard-bore Ascend 1.1 GHz NMR magnet.
For many years, high-resolution NMR was limited to a magnetic field of 23.5 Tesla, equivalent to a 1H resonance frequency of 1.0 GHz. This limit was set by the physical properties of metallic, low-temperature superconductors (LTS), and it was first reached in 2009 with an Avance® 1000 spectrometer at the Ultra-High Field NMR Center in Lyon, France.
High-temperature superconductors (HTS), first discovered in the 1980s, open the door towards even higher magnetic fields at low temperatures, but considerable challenges in YBCO HTS tape manufacturing and in superconducting magnet technology made further UHF progress daunting until recently.
Bruker's novel high-resolution 1.1 GHz magnet achievement now demonstrates the viability of new LTS-HTS hybrid magnet technologies with enormous technological progress in the areas of HTS materials manufacturing, testing and tape jointing, as well as in UHF magnet stabilization, homogenization, quench protection and force management.
