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.
