Attention NMR - 特別注意事項

When removing or inserting an NMR tube into the magnet, keep your eyes on the tube and the warning signs ahead. Before each sample

 insertion into the magnet, please consider the following:

1. What would happen if the NMR tube, empty spinner, and depth gauge are individually inserted into the magnet?

2. How can these individual items be removed? Can they be lifted out?

3. What would be the consequence if a sample with a spinner is inserted into the magnet without lifting it out first?

4. What would be the consequence if the tube is inserted into the magnet without being wiped clean?
