Abstract
In a process for analyzing a sample of unknown constitution by an analytical apparatus, a set of analytical measurements and a set of reference measurements, each comprising a set of multivariate signal responses obtained from a set of samples by a first and a second analytical apparatus, are adjusted to remove operational variabilities associated with the apparatus, thereby providing a first and a second matrix of adjusted signal responses. Via the use of matrix manipulations, a calibration useful for analyzing the signal responses obtained from the sample of unknown constitution by the first analytical apparatus is constructed and applied to the signal responses from the sample to determine its constitution.
