  • Rapid quantification of components in solid mixtures of chemicals via time-domain NMR spectroscopy
    Patent number: 10697911
    Abstract: There is described a method for determining the relative quantities of the expected components in a multi-component mixture of solids. The proposed quantification method makes use of a time domain nuclear magnetic resonance (TD-NMR) spectrometer and requires that, for each of the expected components in the mixture, a T1 saturation recovery curve (SRCi) is measured and recorded. The saturation recovery curve for the mixture sample (SRCmix) is determined from a measurement of the sample with the spectrometer. The relative amounts of the expected components present in the mixture sample are determined by fitting a linear combination of the component SRCs (SRCi) to the SRCmix. The resulting value of each weighting coefficient in the fit provides the relative proportion of the corresponding component in the overall sample.
