1. A method of determining a NMR prediction result of a sample, the method comprising:

  • receiving a plurality of NMR spectra and a corresponding plurality of predetermined measured parameters, wherein each of the plurality of NMR spectra corresponds to one of the plurality of predetermined measured parameters;

    identifying a section of a ppm range in each of the plurality of NMR spectra having a non-stationary peak;

    determining a modified data point for each of the plurality of NMR spectra based on its respective data points in the identified section of the ppm range such that the modified data point being a weighted average value of the respective data points in the identified section;

    replacing the identified section of the ppm range in each of the plurality of NMR spectra with its respective determined modified data point to generate a corresponding plurality of modified NMR spectra;

    determining a modified calibration vector based on the plurality of modified NMR spectra and the plurality of predetermined measured parameters;

    receiving a measured NMR spectrum of the sample;

    identifying a section of a ppm range in the measured NMR spectrum having a non-stationary peak;

    determining a modified data point for the measured NMR spectrum based on data points in the identified section in the measured NMR spectrum such that the modified data point for the measured NMR spectrum being a weighted average value of the data points in the identified section in the measured NMR spectrum;

    replacing the identified section in the measured NMR spectrum with the modified data point for the measured NMR spectrum to determine a modified measured NMR spectrum; and

    determining the NMR prediction result of the sample based on the modified measured NMR spectrum and the modified calibration vector.
