  LOADING THE SPECTROMETER
 

Now that you have a properly prepared sample, and have decided on the experiment you will run, it is time to load the sample into the spectrometer so that you can actually start the run.

Position your tube in a spinner turbine.
  The NMR sample, in its tube, sits inside a large superconducting magnet. It is important that the tube be clean, with no liquid or sticky residue on the outside. NMR tubes are delicate (and expensive!); be sure to handle them carefully.
  NOTE: Spinner turbine designs vary with spectrometer manufacturer. The illustrations associated with the section below show Bruker turbines. If you are using a different system, your spinners will look different, but the positioning procedure will be similar.
Select a spinner turbine. Hold the turbine with the wide end up.
Hold the NMR tube in your other hand, with the cap at the top. Slide the tube into the turbine, positioning the turbine about halfway up the tube.
Place the tube and turbine into the depth gauge. The tubine will rest on top of the gauge. Push the tube down until it touches the bottom. Take the tube and turbine out of the gauge. Return the gauge to the lab bench so that the next user can find it easily.
