Abstract
The method to eliminate background in the case of quantitative multidi mensional spectroscopy, chromatography or any analytical 3-dimensional technique is shown. The 3-dimensional signal is required to be propor tional to the concentration of determined substance and the additivity of signals should be obeyed. Eliminated background is assumed to be a low-order polynomial of two variables. The intensian method is a gene ralization of the Beer-Lambert law, where a certain determinant called intensian replaces absorption and absorptivity. In practice there wil l be no need to use determinants, since usually they are replaced by e xpressions of few terms. Some details on the practical use of the meth od are given.
