Abstract

In the case where a peak on a mass spectrum is saturated due to, for example, signal saturation in a detector or an amplifier provided downstream thereof, a data processor performs fitting with a Gaussian function using data included in the rising part and the falling part (range A) of the peak which are not affected by the saturation, to thereby obtain a desired approximate peak shape B. Then, a mass spectrum in which the saturated peak is replaced with the approximate peak thus obtained is created, the mass-to-charge ratio of the peak top is calculated for this mass spectrum, and this mass spectrum is then displayed on a display screen. Moreover, an extracted ion chromatogram is created on the basis of information on mass-to-charge ratio to intensity of this modified mass spectrum and displayed.
