A basic NMR training is required before a user is granted with NMR access. Please consult with the NMR training page. If you wish to conduct NMR experiments with different sample temperatures, IMSERC staff is the ONLY personnel who may train you how to do this. To apply, simply reserve your experiment time and coordinate with Yuyang or Yongbo to make sure he is available when you start. This should take less than 15 minutes.
Reporting broken glass
To ensure that the NMR’s remain available and performing at a high level, users must report to IMSERC staff any incident involving broken glass around NMR instruments, whether you broke something yourself or observe broken glass in the NMR area. For the manually run instruments, if you realize that the lock sample is not in the magnet with the instrument locked when you arrive, you must report the issue immediately so the we can determine proper next steps to avoid long service interruptions. The policies ensure that the delicate glass pieces inside the spectrometer are not damaged and that users are leaving spectrometers ready for the next experiment. Failure to follow these policies can result in days to weeks of downtime as probes must be inspected for contamination, or worse yet, sent back to the vendor for repair.
If you break glass and report to us, you are helping us to bring the instrument to service at earliest possible time and there will never be any punishment for making a human mistake. Failure to report issues like the ones listed above are one of the few policy breaches that can result in suspension of NMR privileges. We prefer that you call an NMR staff member or Director to set up a response after a problem, but email is acceptable if you cannot reach someone.
When broken glasses is not reported, we assume there is glass pieces inside probe. To check and clean up the probe, we have to take down the system. The first unpleasant consequence of doing so is the instrument down time, which could easily be a few days for system with cryoprobe. In addition, we take increased risk of damaging parts or possibly not being able to bring it back online. In these cases, IMSERC staff will be following up with users who either broke the glassware originally or subsequent users who fail to report an issue with lock samples or visible glass in the NMR area.
