A couple more items worth noting based on crap that’s happened:
Always keep a couple different saved shim settings on file. With numerous people around and lots of different kinds of samples it’s common for shims to get completely out of whack. Having a “Load Std-1” around is always very helpful.
Make sure you’ve posted all the required systems that need to be active in order for the NMR to function properly. There are a lot of different things that can be “down for maintenance” that will basicly shut down the NMR. In my facility that includes: AC power-line outside of range, house air, house cool water, Air Conditioning unit down, and N2/He levels low. We were trained to check all of these things rather than to rely on the instrument to say something was wrong. Often times we get those notes saying that such and such is down for maintenance, and don’t put it together that it knocks the NMR offline.
Post NMR-tube labeling techniques. I personally like rubber band and paper. It only takes one post-it note to leave glue on a tube to mess up the NMR intake system or the air spinning mechanism.
Lastly, congratulations on getting an NMR system. They add a ton of teaching value and generally lot of value to the department. Let local companies know. Around here a lot of universities rent time on their NMRs to pay for supplies and maintenance. It’s about $100/sample here. That’s a lot of student tubes and solvents.
Any good lessons learned from the installation or operation of an NMR from a safety standpoint. We are just about to start installing a new unit and besides the manufacture specs and my CIH’s recommendations, I wanted to reach out there and see if anyone has any good tidbits.
