Problem with Shimming back to 1H after F-NMR (0 replies)

Hello,

I have problem with shimming back NMR instrument to 1H after my 19F NMR experiment and when other students after me want to use it, they always have problem with shimming and it is hard to shim the instrument. I tried after tune it back to 1H shim it with D2O solvent or chloroform solvent but still people say they cant find the shim soon. Please let me know if you can help me to solve the problem!

Thanks
Nazi

[Question from NMRWiki Q&A forum] Problem with the gradient shimming Problem with the gradient shimming Dear Friends, I've recently encountered a problem with gradient shimming that has never happened to me before. I can't clearly determine what caused it but it certainly didn't involve anybody manipulating with the probe. Here's the symptom: when running the gmapz experiment, the Z-profiles (before and after gradient) look like this: http://img833.imageshack.us/img833/2213/zprofilef.png As you can see the second profile (after the gradient) is distorted at the left edge (more or less severely, depending on a sample - here it's just a tiny "step")....	nmrlearner	News from other NMR forums	0	10-11-2011 06:35 PM

[NMR analysis blog] Back in the blogosphere Back in the blogosphere After a 3 month-long hiatus, I'm back in the blogosphere. I’ve been travelling and working very hard on several exciting projects, but my entries have consequently suffered. Although my workload has not decreased, I am not planning to travel for the next few weeks. Hopefully I will manage to blog on a more regular basis from now on, especially now that there are many things we have been working on lately that I hope will be of interest to the NMR community. For now, I’d just like to point out a very interesting blog entry written by my friend Stan on his...	nmrlearner	News from NMR blogs	0	08-21-2010 09:12 PM
