Patent ID: 7847547

Claim:
A concentration determining device comprising: a processor; and a non-transitory computer-readable medium operably coupled to the processor, the computer-readable medium comprising instructions that, when executed by the processor, perform operations comprising (a) identifying a plurality of compounds in a mixture based on intensity peaks identified from nuclear magnetic resonance (NMR) data generated from the mixture; (b) selecting a compound from the identified plurality of compounds for a concentration determination; (c) determining a concentration equation associated with the selected compound, wherein the concentration equation is defined based on a regression curve fit to a plurality of data points, wherein the plurality of data points are intensity peak values calculated using second NMR data generated for a plurality of reference samples of known concentration levels of the selected compound, (d) selecting a first peak associated with the selected compound from the NMR data generated from the mixture, wherein the selected first peak does not overlap with a peak associated with another compound of the identified plurality of compounds; (e) determining an intensity value associated with the selected first peak; and (f) calculating a concentration value of the selected compound in the mixture using the determined concentration equation and the determined intensity value.
