Patent ID: 7529629

Claim:
A method for analyzing data obtained from at least one sample in a measurement system that has a capability for measuring components of a sample containing more than one component as a function of at least two different variables, said method comprising: obtaining data representative of at least one sample from said system, said data being expressed as a function of said at least two variables; forming a data stack having successive levels, each level containing one of said data samples; forming a data array representative of a compilation of all of the data in said data stack; and separating said data array into a series of matrixes in one overall decomposition process, said matrixes including: a concentration matrix representative of concentration of each component in said levels of data; a first profile of the components as a function of said first variable; and a second profile of the components as a function of said second variable; and at least one standardization matrix serving to calibrate one of said concentration or profile matrixes.
