NMR Chemical Shift Standards

NMR Chemical Shift Standards are compounds of which give rise to a NMR signal of known chemical shift.

NMR Reference Standards

NMR Reference Standards are chemically-defined solutions packaged in flame-sealed NMR tubes designed to test certain aspects of spectrometer performance.

Reference Materials for qNMR

Reference materials (RMs) for qNMR are used as either internal or external standards for purposes of quantitation. RMs used as internal standards need to be highly pure, chemically inert, non-hygroscopic and non-volatile, give rise to simple spectra with non-overlapping resonances of the sample and be soluble in common deuterated NMR solvents.
