  • Patent number: 7847547
    Abstract: A method of determining a concentration level of a compound in a mixture is provided. A plurality of compounds are identified in the mixture based on intensity peaks identified from NMR data generated from the mixture. A compound is selected from the identified plurality of compounds for a concentration determination. A concentration equation associated with the selected compound is determined. A first peak associated with the selected compound is selected from the NMR data. The selected first peak does not overlap with a peak associated with another compound of the identified plurality of compounds. An intensity value associated with the selected first peak is determined. A concentration of the selected compound in the mixture is calculated using the determined concentration equation and the determined intensity value.
