World’s Fastest 111 kHz Magic-Angle Spinning (MAS) Probe Enables
Highest Performance
NMR Analysis up to 1 GHz on Biological Solids and Materials with
Unprecedented Convenience
ASILOMAR, Calif.--(BUSINESS WIRE)--
At the 56th Experimental Nuclear Magnetic Resonance Conference (www.enc-conference.org),
Bruker (NASDAQ: BRKR) this week is introducing a unique, new ultra-high
speed MAS probe together with a new MAS III
controller. The new 111 kHz MAS probe, with 0.7 mm sample diameter and a
sample volume of 500nl, which has been demonstrated up to 1 GHz proton
frequency, delivers excellent sensitivity and the fastest spinning
frequency available on the market for access to new applications in the
solid-state NMR analysis of biosolids, as well as in materials science.

Solid-state NMR is a growing discipline, providing unique structural and
dynamics information on various materials and biological solids in their
native state, such as membrane-embedded proteins. The additional
spectral resolution provided by very fast Magic Angle Spinning (MAS)
allows novel detection techniques for structural and functional
characterization of complex molecules. The new 111kHz CP-MAS probe will
be useful for large, rigid proteins and those with paramagnetic centers
in solid phase, and for the structure elucidation and improvement of
advanced materials, such as battery components.
The new 111 kHz CPMAS probe extends the Bruker line-up of high speed MAS
probes, comprising of 1.9 and 1.3 mm probes, now with a 0.7mm MAS
system. This gives researchers great flexibility in terms of sample
volume and spinning requirements, depending on the sample of interest. A
new control unit, the MAS III, ensures stable regulation
even at very high rotation rates. The 111 kHz MAS probe is available for
Bruker standard-bore and wide-bore NMR magnets and comes with dedicated
tools for convenient filling and handling of the small diameter rotors
and caps.
"The ultra-fast magic angle spinning capabilities of Bruker’s 111 kHz
MAS probe allows for the direct and high resolution observation of
proton resonances from complex biomolecules,” stated Professor Lyndon
Emsley from the Ecole Normale Supérieure de Lyon, France. He continued:
”We get double the resolution in protonated samples compared to 60 kHz
spinning, and we were especially pleased to obtain a 1 GHz version of
this break-through MAS probe, with which we have measured
never-before-seen ultra-high field, ultra-fast MAS data. As such, it is
a great new tool in our solid-state NMR arsenal for the structure
determination of proteins, a critical need for studying disease
mechanisms."
