Important Facts When Purchasing a Solids Probe

Important Facts When Purchasing a Solids Probe

  1. Do you expect to be doing long acquisitions with high-power decoupling at over 400 MHz on lossy samples?  If so, then you want a probe in which the 1H field is not generated by a solenoid.  The DE coils on Doty BMAX probes  work well for these applications.
  2. Is proton efficiency or X/Y performance the most important for your experiments?  Doty’s new BMAX probe is optimized for X/Y performance, while still providing excellent decoupling.
  3. How fast do you need to spin?  The DI-3 spins 28 kHz, compared to 18 kHz for the DI-4, but the DI-4 may give you nearly twice the S/N.
  4. Will you need two channels (H/X) or three (H/X/Y)?
  5. What nuclides are of interest on the X/Y channels?
  6. What temperature range do you need?  (Doty sample-temperature options range from -170°C to the Doty High Temp probe at +700°C.)

  • You can perform Extended VT MAS/NMR in a narrow bore magnet. Choose from three VT ranges with Doty’s 3, 4, or 5 mm spinners:

Standard NB VT range: -80 oC to + 120 oC

Extended NB VT range: -150 oC to + 150 oC

Low Extended NB VT range: -170 oC to + 150 oC


  • State-of- the- art Doty probes have Si3N4 and non-magnetic alloy construction.  This provides for the Lowest background signals. Minimal 13C, 1H, 19F, 27Al,  29Si,11B, 15N, 23Na, 2H, 17O, …
