Isotopic
Isotopic
Deuterated solvents are manufactured for use with NMR instruments. These solvents contain high chemical purity and maximum isotopic enrichment.
Deuterium signals from these solvents are used for an NMR lock system (also known as frequency-field lock) to avoid the fluctuations of the NMR magnetic field by off-setting the effect of natural drift. In order to provide deuterium lock, the NMR constantly monitors the deuterium signal resonance frequency from the solvent and makes changes to the magnetic field to keep the resonance frequency constant.
