High Field NMR

Paolo brought to our attention an issue of cold probe shimming using topshim with our shared 700 (Bio NMR lab). The sample is protein in 90% H2O about 300ul in Bruker Shigemi tube. When we center the shigemi tube with the depth gauge coil center marking topshim B0 standard deviation after shimming is anywhere between 5 to 10 Hz. Seho and I could reproduce this observation.
