Claim 3:
4. The method of claim 1, further comprising using the standardized analyzer spectral responses for calibration of the plurality of spectroscopic analyzers, and wherein the step of using the standardized analyzer spectral responses comprises:
using one or more spectral models from the first spectroscopic analyzer when in the first state to calibrate one or more of the remainder of the plurality of spectroscopic analyzers; and
determining portfolio sample-based corrections for the one or more of the remainder of the plurality of spectroscopic analyzers based at least in part on the standardized analyzer spectra portfolio and second-state portfolio sample spectra, so as to define the one or more of the remainder of the plurality of spectroscopic analyzers as being in the second state.
