摘要：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 dataprocessor 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, tothereby obtain a desired approximate peak shape B. Then, a mass spectrum in which thesaturated 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 massspectrum 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 intensityof this modified mass spectrum and displayed. Accordingly, even in the case where peaksaturation occurs, the accuracy of the mass-to-charge ratio for the peak is improved, andthe accuracy of compound identification and compound structure estimation using a massspectrum or quantitative properties using a peak area value (integral value) are improved.
