Building a Cost-Efficient High-Pressure Cell for Online High-Field NMR and MRI Using Standard Static Probe Heads: An In Situ Demonstration on Clathrate Hydrate Formation.

ABSTRACT: High-pressure nuclear magnetic resonance (NMR) spectroscopy finds remarkable applications in catalysis, protein biochemistry and biophysics, analytical chemistry, material science, energy, and environmental control but requires expensive probe heads and/or sample cells. This contribution describes the design, construction, and testing of a low-cost 5 mm NMR tube suitable for high-pressure NMR measurements of up to 30 MPa. The sample cell comprises a standard, 5 mm single-crystal sapphire tube that has been fitted to a section of a relatively inexpensive polyether ether ketone (PEEK) HPLC column. PEEK HPLC tubing and connectors enable integration with a gas rig or a standard HPLC pump located outside the stray field of the magnet. The cell is compatible with any 5 mm static NMR probe head,
