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.
