Abstract
Spectrographic instruments at remote site locations measure near infrared absorbance spectra for unknown materials and transmit the absorbance spectra to a central web site where, the measurements are standardized to be the same as if they were measured by a master instrument. The standardized absorbance spectra are then compared with a library of spectra stored at the central web site to select a subset of absorbance spectra from the library which most closely correlate with the absorbance spectrum received from the remote sites. The library spectra are obtained from measurements on materials, the measurable characteristics of which are known. From the selected subset, equations are developed relating the measurable characteristics of the unknown material to the absorbance spectra and from these equations, the measurable characteristics of the unknown materials are determined. The results of this analysis are then transmitted back to the remote site locations electronically.
