Weigh or dispense about 10 - 20 mg of sample into a 4/5 dram
vial. |

Measure about 3/4 mL of solvent using a
disposable pipet. It should look like about this much. |
Pipette solvent into vial and draw mixture back and forth until
a solution is made. |

Dispense solution using pipette into the NMR tube. The
depth of solution should be about 3 cm. |
The tube is then fitted with the spinner, and tube and spinner
are placed into the depth gauge. This puts the spinner at the correct height. |
Spinner (left) and depth gauge (right) |
After depth gauging it, the tube should look like this

The sample should look like this in the chamber. |
Load ICON-NMR on the computer console for the Bruker 400 FTNMR
system in Gilbert 228. Consult the directions for using ICON-NMR (separate handout.) |

The program will automatically shim the sample. |
Once shimmed the FID will be collected |

The FID will be transformed, phased and integrated for you
and a hardcopy will be printed. |
