METHOD FOR ANALYZING AN UNKNOWN MATERIAL AS A BLEND OF KNOWNMATERIALS CALCULATED SO AS TO MATCH CERTAIN ANALYTICAL DATA AND PREDICTING PROPERTIES OF THE UNKNOWN BASED ON THE CALCULATED BLEND

摘要

A method for determining a property of an unknown material including the ste ps of determining the IR spectrum of the unknown material, fitting the IR spectrum to a linear combination of known spectra in a database, wherein a database includes spectra of reference materials whose assay properties are known, and determining the property of the unknown material from the assay properties of the reference materials.
