| Abstract: | A method for measuring the isotopic ratios for various elements based on the calculation of peak areas is proposed. The areas
of peaks are calculated by means of approximation of an experimental signal by a phenomenological peak-shape model, which
takes into account the physical principles of detecting signals of sector mass spectrometers. The method is simple to implement
and allows measurements of the isotopic ratios when standard measurement techniques are inapplicable and/or do not yield the
desirable accuracy, e.g., because of an insufficient resolution of the mass spectrometer. |
