Basic Anasazi Proton NMR Tutorial
Running the Basic Shimming Program
Load the water sample. Click on the PNMR window and type 'shim' at the 'H1>' prompt, then
press the Enter key. Follow the instructions on the screen as the program runs. Be careful when
adjusting the Y and 'CURV' settings. Entering an incorrect value won't hurt the instrument, but it
will confuse the shimming program and require longer to complete a valid shim.
When the shim program completes, load the ETBZ sample again and run a spectrum. Look at
the spectrum in NUTS and check the TMS peak again for splitting. It should display a single
peak within the target range. Note that the peak may not be completely symmetrical, but this is
OK for the majority of samples that will be run on this instrument.
