ABSTRACT:
When a standard specimen including a given reference component is analyzed after a separation condition is changed, a data processing section (31) acquires an actual measurement value of a peak of a reference component that appears in a chromatogram obtained by the analysis, and estimates a deviation of the retention time of a peak of an intended component on the basis of the actual measurement value and information on the retention time of the reference component before the separation condition stored in an analysis condition information storing section (34) is changed, to correct a measurement time range of the respective ion sets of an SIM measurement parameter which is stored in an analysis condition information storing section (34). An SIM measurement is conducted according to the parameter that is corrected when analyzing the intended specimen, to thereby make it possible to conduct a desired measurement by an operator.
