    Abstract: A method for determining a calibration function includes: calculating a first distance, between a distribution of target spectra and a comparison distribution of spectra; calibrating the distribution of target spectra with a first preliminary calibration function to form a first distribution of calibrated target spectra; calculating a second distance, between the first distribution of calibrated target spectra and the comparison distribution of spectra; determining that the second distance is less than the first distance; and setting the calibration function equal to the first preliminary calibration function.

    Abstract: A method of quantifying an amount of a substance in a sample of material for a delivery system, the method comprising: obtaining first near infra-red spectroscopy data for the sample of material in a first wavelength range; obtaining second near infra-red spectroscopy data for the sample of material in a second wavelength range, wherein the second wavelength range is separated from the first wavelength range; and using the first and second near infra-red spectroscopy data to estimate an amount of the substance in the sample of material.
