Sensitivity Boost for Solid State NMR

Dynamic Nuclear Polarization (DNP) can be used to increase the sensitivity of NMR experiments by transferring the much higher polarization of unpaired electrons spins to nuclear spins. This polarization transfer is driven by high frequency microwave irradiation.

The Bruker BioSpin 263 GHz solids DNP spectrometer consists of five main development areas:
 

• 25 W 263 GHz gyrotron tube
• 9.7 T gyrotron magnet with superconducting gun coil
• Control system hardware and software, power supplies and cooling networks
• 263 GHz microwave transmission line from gyrotron to NMR sample´
• Low temperature MAS probe with built-in waveguide and cold gas supply

These components are assembled with a standard 400 MHz WB solids spectrometer.

The 263 GHz gyrotron and accessories have been designed specifically for extended DNP-enhanced solids NMR experiments. The control system monitors the gyrotron for stable and safe operation and provides an easy user interface.
 
For the first time, our unique high power 263 GHz gyrotron (25W CW) allows DNP to work at high field. The well proven microwave guide technology of our EPR product lines ensure optimum beam propagation and high polarization efficiency. Together with our new low temperature MAS probe technology it brings unsurpassed sensitivity to your solid state NMR applications.

HyperQuant™ is a benchtop time-domain NMR reader that precisely and quantitatively delivers both the magnetic hyperpolarization and thermal polarization status of a sample.

All of this capability available from Bruker, your ideal research partner in Dynamic Nuclear Polarization.
