With Bruker's Topshim program, I have used the following command to shim every new sample:
topshim z6 1d optsolvent coil=1H tuneb tunea
Now I'd like to use IconNMR to automate this procedure, but can't find much information in IconNMR Automation Guide User Manual (Version 001). It mentioned "TOPSHIM_WITH_AUTOSHIM" in 3.11.2.1 yet still not clear how to execute a custom command.
I have a question not an answer.
I imagine the shimming auto-optimization operates like autofocus in older cameras.
In that case wouldn't the optimization take considerable time?
Thank you Clemens Anklin
. I did find the "Edit Lock/Shim/ATM" option, checked it, and now able to set shimming commands for different samples.I ended up using topshim z6 1d optsolvent tuneboff tunea for experiments with p3919gp solvent suppression, and found it resulted better peak shapes than the default topshim.
Hi Clemens Anklin
. I did try tuneaxyz but could not see any difference. It may have taken less time although I didn't really watch the time. Speaking of time, I do wonder if there is a way to start acquisition at an exact time, i.e., to set aside enough time for sample loading/locking/atm/shimming etc. and start the acquisition (as if issuing the zg command in topspin) at exactly hh:mm:ss.I thought tunea by default would do more shims (XZ and YZ) than tuneaxyz?
Does ordmax=8 get you shims on z8? How do I know if I have a SmartProbe to handle this?
If (automatic) optimization of field uniformity is an iterative process it may take time. As for as I can understand it, the optimization must be done every time for a new sample.
