摘要： In the case where a given mass range is repeatedly scanned to sequentially create mass spectra and create a mass chromatogram or the like, when a number of data, which are arranged on the mass axis and constitute a mass profile of the given mass range, are collected for a predetermined number of the alignment (S1 and S2), a two-dimensional filtering process is performed by correcting the target data, for each data aligned in the mass axis direction, using the data contiguous before and after in the mass axis direction and the data contiguous before and after in the time axis direction (S3). For the mass profile constituted of the data thus processed, a peak detection is performed (S4) and the peak's mass number is determined to create a mass spectrum (S5). Consequently, the mass numbers' fluctuation in the mass spectrum is moderated, the mass resolution is increased, and the accuracy of the mass chromatogram is also increased.
