World’s First 950MHz Magnet for Nuclear Magnetic
Resonance At Field
Oxford, Sept 9:
Oxford Instruments Superconductivity (LONDON
OXIG) announces the world’s first commercial 950 MHz magnet is now at field
and being prepared for delivery to Oxford University in September 2005. The
system, which was sold directly to Oxford University, is demonstrating excellent
all round performance. The base drift rate is less than 5 Hz per hour -a
fundamental parameter for long-term biomolecular NMR experiments and crucial in
obtaining excellent data.
The 950 MHz system also validates the company’s
new, proprietary, niobium-based superconductor, developed to provide enhanced
critical current density capacity (Jc). The introduction of this new
superconductor is a major breakthrough as it provides the additional current
density necessary for the development of compact Ultra High Field NMR magnet
systems. This technology also provides a significant competitive advantage for
Oxford Instruments, alleviating the dependence on developing exotic high
temperature superconductors, which would otherwise be required to achieve the
same field strength.
These new proprietary conductors, combined with
‘femto Ohm’ superconducting jointing technology, are key elements required to
achieve stable operation. This technology has also enabled the company to
achieve rapid time to market for a unique range of ‘compact’ magnets, such as
the Actively Shielded AS800MHz system, and is key to the success of the 1GHz
programme.
Once installed, the 950 MHz magnet will provide
the University’s NMR Protein Structure Group with the highest degrees of
sensitivity and resolution ever available for NMR spectroscopy. This will allow
data collection and analysis of biomolecules over 100 kDa in size, proving the
team with new insights into the structure and intra-molecular interactions of a
wide range of proteins.
This announcement follows Oxford Instruments’
recent initiative to supply NMR magnets directly to the end user market place,
effectively reducing third party pricing margins.
