FINE SHIMMING

Parameters:

probe = Z168276_0016
solvent = H2O+DMSO
shim nucleus = 1H
nucleus optimised for = 1H
o1p (set) = 4.70 ppm

Results:


1D Shimming:
Iteration 1: FWHM Before= 5.0 Hz, Target= 0.4 Hz, After= 0.2 Hz
Iteration 2: FWHM Before= 0.2 Hz, Target= 0.4 Hz, After= 1.6 Hz
Iteration 3: FWHM Before= 1.6 Hz, Target= 0.4 Hz, After= 0.3 Hz
Iteration 4: FWHM Before= 0.3 Hz, Target= 0.3 Hz, After= 0.5 Hz
Iteration 5: FWHM Before= 0.5 Hz, Target= 0.3 Hz, After= 0.4 Hz
Iteration 6: FWHM Before= 0.4 Hz, Target= 0.3 Hz, After= 0.3 Hz
Slow convergence detected. Shimming was aborted.
Using the best result as the final shim state.

Lineshape quality factor (1D spectrum, non-spinning) = 0.559


Performing tune after shimming

NOTE: The lock signal appears to be unstable. This affects the performance of the tune algorithm! 

tune lock level increase = 1.0
