Claim 26:
27. A spectroscopic analyzer controller to determine and use standardized analyzer spectral responses to enhance a process for calibration of a plurality of spectroscopic analyzers such that for a given material each of the plurality of spectroscopic analyzers outputs a plurality of signals indicative of a plurality of material properties of the material, the plurality of material properties of the material output by each of the plurality of spectroscopic analyzers being substantially consistent with one another, the spectroscopic analyzer controller being configured to:
receive one or more signals from a first spectroscopic analyzer when in a first state during a first-state time period;
determine one or more spectral models based at least in part on first-state sample spectra for each of a selected plurality of multi-component samples and corresponding sample data;
output a standardized analyzer spectra portfolio for a selected one or more first-state portfolio samples;
output, based at least in part on one or more signals received from the first spectroscopic analyzer when in a second state during a second-state time period, a second-state portfolio sample spectrum for each of a selected one or more second-state portfolio samples;
transfer the one or more spectral models from the first spectroscopic analyzer when in the first state to a second spectroscopic analyzer; and
determine portfolio sample-based corrections for the second spectroscopic analyzer based at least in part on the standardized analyzer spectra portfolio and the second-state portfolio sample spectra, thereby to standardize the second spectroscopic analyzer.
