| Although some of the earliest applications of Nuclear Magnetic Resonance Spectroscopy involved quantitative analysis of mixtures, NMR is still regarded primarily as a qualitative tool for the elucidation of molecular structures. Additionally, most published quantitative procedures involve the use of toxic solvents, such as CDCl3, or carcinogenic compounds, such as benzene. The relative concentrations of a mixture of anhydrous ethyl alcohol and acetone in D2O can easily be determined using 1H NMR. Furthermore, a mixture of one of these anhydrous compounds and a sample of the other compound containing water can be analyzed to determine the amount of water present in the second solution component. |
