Even the smallest contamination on an NMR tube can significantly impact your results. A dirty sample can lead to: - Poor shimming and reduced sensitivity - Potential contamination of the probe, requiring time-consuming maintenance #NMRchat #ChemSky #RealTimeChem
Illustration of the effect of dirty NMR tubes. The top shows a clean NMR tube and the corresponding "shim-map", which is very homogeneous. The bottom shows an NMR tube with a small black marker dot. The corresponding shim map shows a clear perturbation of several Hz around the dot.
