Picture of a golden NMR coil.

The coil is the heart of every NMR probe. It is used to send pulses and receive signals from the NMR-active nuclei. Its material and design directly affect NMR resolution and sensitivity, making it a crucial component of any NMR spectrometer.

#NMRchat if you’re flying into SFO Sunday morning for #ENCISMAR2025, I can offer a ride to Asilomar for 2-3 people. Info already on the transportation matching G-sheet.

As shown in the images, even a tiny mark on the tube can distort the 3D shimming map, affecting data quality. Always handle your samples with care-clean tubes mean better spectra and fewer instrument issues!

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.

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
