Abstract
A method for the determination and correction of background signals in a spectrum, consisting of signals of a plurality of spectral points, characterized by the steps of: Calculating at least three statistic or analytic functions of the signal values of the spectrum, attributing probabilities P(band) for the presence of bands to each point in each of the calculated functions: Adding the probabilities P(band) up to an overall probability ΣP(band) from all calculated functions for each point; calculating a probability P(background) for the presence of background for each point in the spectrum from said overall probability ΣP(band) according to P(background)=1−ΣP(band) wherein negative values are set to zero; and calculating a fit of the signal values at all points of the original spectrum wherein the signal in each point is taken into account in the fit only with the respective probability for the presence of background P(background), and subtraction of the background function determined in such a way from the signal values of the original spectrum in order to generate a background corrected spectrum.
