* NMR Sample Tube or 'Tube' - A thin glass tube (~5mm thick) and about 7" long. Your sample is placed into this tube. | |||
* Sample Spinner - Before your NMR tube can be placed into the intrument's probe, the Sample Spinner (a white piece of plastic) needs to be placed around your NMR tube. This keeps the tube centered inside the probe (which has a much wider diameter than the your NMR sample tube). | |||
* Probe - The detector of an NMR. Most commonly, this is Hydrogen-1, but probes for other isotopes exist. The probe is ultimately just a coil, but it is tuned to the isotope of interest. There are "wideband" probes that can be tuned to various isotopes as long as they are NMR active. | * Probe - The detector of an NMR.
