Reference Standards Quality in NMR Spectroscopy

Because many conclusions based on NMR spectrometry require optimal performance or a gauge of current spectrometer performance, spectroscopists have come to rely upon the spectra of certain carefully prepared chemical mixtures to evaluate and compare performance characteristics. These mixtures, called Reference Standards or Test Samples, are made in a myriad of recipes to cover different nuclei, concentration ranges, performance criteria, and sample or tube sizes, to name a few.
