VARIAN 500 - NMR CHECKLIST

1.  Know the configuration of the different probes and what can be run on each    – advantages and disadvantages – look at bottoms – differences.

2.   How to tell which probe is in – requesting probe changes, importance of labeling which probe in filename or text.

3.  Differences in manual shimming and gradient shimming (do not use top bar setup first time).

4.  Shimmap (and how to check it) vs. shimfiles – differences, storing your own shimfile (svs)

5.  VT  system – how to tell the temperature – emergency tube eject

                                                                                     emergency VT off                     

 VT always on – location of FTS and what it is simple VT  - temperature changes from  10  to  50 C (lesson needed first time you run cold VT).

6.  Tuning the probe -  {su} ,  channel  1 ,  channel 2,  frequency window when to STOP,  what is “good”.
