Phoenix NMR Announces Our MAS-DNP Probe

January 3rd, 2020 Posted by Products No Comment yet

Phoenix DNP Probe

Dynamic Nuclear Polarization (DNP) signal-enhancement capability is now available in combination with innovative Phoenix Solid-State NMR (SSNMR) probe technology to expand the scope and sensitivity of biomolecular and materials SSNMR research at 400-600 MHz. The new Phoenix MAS-DNP probe system utilizes the same robust, professional design strategy that scientists have come to expect in all Phoenix SSNMR probes and accessories.

DNP Enhancement of 13C Proline using Phoenix DNP Probe
13C CP/MAS DNP enhancement of 42:1 was measured using a PhoenixNMR 395 GHz/600 MHz DNP HFXY probe fitted with a 2.5 mm spinning module. Sample Temperature = 150 K; MASS = 25 kHz. The sample was prepared using 10 mM AMUPol biradical and “DNP Juice” = d8-Glycerol/H2O/D2O at a 6/3/1 ratio.

Overview of the Phoenix DNP Innovation

  • Add a new Phoenix DNP probe to expand capability on an existing DNP SSNMR instrument; or
  • Add a Turn-key DNP System, including gyrotron, to an existing 9.4 – 14.1 T, Wide-Bore SSNMR instrument, pairing the robust Phoenix NMR probe technology with Bridge12 Technologies components to complete the DNP package;
  • Combine DNP with HFXY and HFX probe configurations;
  • Optional Probe Accessories allow low-gamma nuclei and/or simultaneous H/F operation;
  • Operating Temperature Range is 90 K to 373 K (actual sample temperature is dependent on spinning speed);
  • 2.5 mm MASS Module is available for spinning speeds up to 25 kHz;
  • Insert and Eject Samples In-Situ at cold and warm temperatures;
  • Modest up-front Costs beat other commercially-available DNP probe systems;
  • Unique VT Design minimizes the use of cryogens to dramatically reduce operational costs.
