New! 900 MHz Data from 1.6mm HFXY PhoenixNMR Probe

May 29th, 2020 Posted by PhoenixNMR, Products, Technology No Comment yet

Below: aliphatic region of the 2D CC spectrum of 15N, 13C labeled alpha-synuclein protein monomer seeded from a brain tissue sample (250 ms CORD mixing), acquired at 900 MHz 1H field at the National Magnetic Resonance Facility at Madison (NMRFAM, @NMRFAM) , utilizing a PhoenixNMR HFXY probe fitted with a 1.6mm module and PhoenixNMR speed controller (PMAS).

The PhoenixNMR HFXY probe was operated in double resonance mode at MASS = 20 kHz; mixing time = 250 ms; total time to acquire spectrum = 20 hrs using 4 blocks of 1024 rows each; 8 acquisitions per row; pulse delay = 1.5 s; CORDxy4 recoupling plus SPINAL decoupling.

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.

Phoenix DNP probe and equipment
PhoenixNMR DNP probe system, showing: a) PhoenixNMR WB HFXY probe, b) PhoenixNMR MAS speed controller, c) PhoenixNMR cryogenic VT and sample insert/eject controller, d) Bridge12 Technologies cryogenic counter-flow heat exchanger. Not shown: 50-liter LN2 Dewar.
Phoenix NMR DNP Enhancement 13C Proline
13C CP/MAS DNP enhancement of 77:1 was measured using a PhoenixNMR 395 GHz/600 MHz DNP HFXY probe fitted with a 2.5 mm spinning module. Sample Temperature = 124 K; MASS = 10 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.
