Claim Text:
1. A data-processing system for chromatographic mass spectrometry for creating a chromatogram by processing data repeatedly collected by a chromatograph quadrupole mass spectrometer capable of setting a mass spectrometric measurement condition for each of segments corresponding to a plurality of time ranges continuously or discontinuously set on a time axis, comprising: a) a memory for storing a parameter value specified as a mass spectrometric measurement condition for each of the segments; b) a determiner for retrieving, from the memory, a predetermined parameter value for each of a pair of continuously located segments, and for determining whether the retrieved parameter values are identical; and c) a chromatogram creation processor for creating a chromatogram by connecting partial chromatograms based on the data collected for each of the aforementioned pair of segments under the corresponding measurement condition, when the determiner has determined that the retrieved parameter values are identical.
