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