The method for estimation of spectral peak parameters

A new economical algorithm for estimating the parameters of signals in mass spectrometry, chromatography, and other applications, representing a sequence of peaks against a noise background, is proposed. A traditional approach for the peak top detection by the intersection the zero line by the first derivative is developing. In order to increase the reliability of detection of the beginning, end, vertex and saddle between peaks, it is proposed to compare the values of the derivatives at three points of the sliding data window.
