Abstract
A method for determining a property of an unknown material including the steps 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.
Claims72
A method for determining an assay property of an unknown material comprising:
- (a) determining multivariate analytical data of said unknown material,
- (b) fitting said multivariate analytical data to a linear combination of known multivariate analytical data in a database to determine the coefficients of the linear combination, wherein said database includes multivariate analytical data of reference materials whose assay properties are known, and
- (c) determining said assay property of said unknown material from the coefficients and assay properties of said reference materials.
