GUIDELINES FOR USAGE OF WIDE-BORE SOLID STATE NMR, 125 SCHRENK HALL

Preregistration Required

• Use google calendar available by clicking “Availability” at the NMR Institute website (https://chem.mst.edu/research/nmr-institute/).
• Please contact Dr. Chariklia Sotiriou-Leventis (cslevent@mst.edu) or Rushi Soni (rus6y2@mst.edu) for pre-registration of solid-state NMR. All solid-state NMR sample acquisitions will be done by Rushi Soni.

Access to the NMR Institute, 125 Schrenk Hall

• The entrance door to 125 Schrenk Hall must remain closed. Open door only to enter and exit. 
• Only NMR samples prepared properly (refer to sample specification and preparation on NMR Institute website) in vials may be brought to 125 Schrenk Hall and submit them to the ss-NMR TA, currently Rushi Soni. No other chemicals or equipment allowed. 

Facilities Hygiene

• Please wear protective face mask for entire time after you enter the NMR room.
• Do not use liquid or spray cleaning and/or disinfecting products on NMR rotor. Those products can leave a residue that might interfere with the measurement or the operation of the rotor, and they may damage the interior of the probe.
• Clean up and sanitize all surfaces you have touched or used including the plastic covers of keyboard and mouse. 
• Discard nitrile gloves upon leaving 125 Schrenk Hall.

Sample specification and preparation

• All samples must be completely dry, finely powdered, non-toxic, non-carcinogenic, non-magnetic, and free from any metals.
• Solid samples can be finely grounded using motor and pestle or a ball-mill if they are hard. Soft and flexible materials need to be frozen using liquid-N₂and then finely grounded into powders.  (Note: Please take extra care not to contaminate samples during grinding).
• Approximately, 0.8 to 1 g of sample is required to completely pack the sample rotor.
• For more detailed information regarding sample preparation, setup procedures, acquisitions, and data processing please refer to: “Solid State NMR AVANCE Solids User Manual, v.003” from Bruker website (https://www.bruker.com).
