Abstract
A system for analyzing a mixture of chemical components. First, a liquid or gas chromatograph produces samples of the mixture. The samples include overlapping components. A spectrometer measures wavelength of each sample. A memory stores the measured wavelengths of each sample as rows in a first matrix. Independent component analysis is applied to the first matrix to obtain a second matrix and a third matrix. Columns of the first matrix are elution profiles of distinct component groups, and rows of the third matrix are corresponding spectra of the distinct component groups.

A method for analyzing a mixture of chemical components, comprising:
- obtaining a plurality of samples of the mixture, in which the samples include overlapping components;
- measuring a plurality of wavelength of each sample of overlapping components;
- storing the measured wavelengths of each sample as rows in a first matrix;
- and
- applying independent component analysis to the first matrix to obtain a second matrix and a third matrix, in which columns of the first matrix are elution profiles of distinct component groups and rows of the third matrix are corresponding spectra of the distinct component groups.
