A method, a portable device and a measuring instrument for standardization of a satellite measuring instrument to a corresponding master measuring instrument are disclosed. The portable device includes a device for containing a reference material, and an information unit for storing information about the reference material and measurements of the reference material on the master measuring instrument. When placed in a satellite measuring instrument, information from the master instrument stored in the information unit of the portable device is transmitted automatically and wirelessly to the satellite instrument and, together with measurements by the satellite instrument of the reference masterial in the portable device, a standardization model for the satellite instrument and the sample type is obtained.

Method and apparatus for standardization of a measuring instrument

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.
