-High Pressure NMR-

High pressure NMR has a long and storied history in physics, chemistry and biophysics. However, historically the method has been greatly limited by the absence of commercial availability of high performance, large active volume NMR sample tubes capable of safe and sustained operation above 1 kbar pressures. Recent installations have been up to 2.5 kbar pressures.


High-Pressure NMR Assembly

ROTOTEC-SPINTEC-EXPL-PROTECT for any NMR / EPR System up to 500 Bar in the case of Varian / Agilent / JEOL / Magritek or in excess of 500 Bar if a Bruker or Oxford Instruments Pulsar system is to be used.

  In recent times the interest in high pressure NMR / EPR has been increasing necessitating the development of an explosion protection chamber to protect the user.
  If the system being used contains no gas and is 100% liquid based as in the case of the Extreme Pressure NMR systems currently running up to 3 kbar, no explosion protection is required as the system cannot explode as per basic physics. However, if a gas is present the risk of explosion is real and is not to be taken lightly.

Doty Scientific - Solids Probes

Solids NMR Doty Scientific, Inc. was founded by Dr. F. David Doty (president and chief engineering scientist) in May 1982, in Columbia, South Carolina, for the primary purpose of designing and manufacturing scientific instrumentation. The company's initial product was a CP/MAS (Cross Polarization/Magic Angle Spinning) probe for chemical structure determination of solid materials via Nuclear Magnetic Reso­nance (NMR).
