Claim One:
1. Method for quantitative assessment of chemical constituents of a substance using reflectance spectroscopy, the method comprising: obtaining a plurality of samples of said substance, the samples having respective chemical constituents; spectrally analyzing each sample of said substance using reflectance spectroscopy, said reflectance spectroscopy obtaining spectroscopy data of said respective sample; applying to said sample spectroscopy data of each respective sample of said substance a plurality of combinations from a set of preprocessing operations; removing ones of said combinations; from each remaining combination generating a respectively different version of said sample spectroscopy data, each version being a respective perturbation of the sample spectroscopy data, each perturbation thereby being generated according to a respective one of said combinations of preprocessing operations, wherein said set of preprocessing operations comprises initial smoothing, multiplicative scatter correction, signal normal variate, absorption, continuum removal, first derivative, second derivative, and final smoothing; using all of said perturbations, generating a model relating said preprocessed spectral data to respective chemical constituents, and using said model with spectroscopy data of an additional sample of said substance having unknown chemical constituents to determine respective unknown chemical constituents thereby characterizing the chemical constituents of said additional sample of said substance.
