Abstract
A chromatograph mass spectrometer according to an aspect of the present invention is a chromatograph mass spectrometer including: a chromatograph unit (LC unit) configured to separate components in a sample; and a mass spectrometer (MS unit) configured to execute mass spectrometry on ions having a specific mass-to-charge ratio derived from a compound for each compound temporally separated by the chromatograph unit, the chromatograph mass spectrometer further including: an analysis condition setting unit () configured to allow a user to input a width of a peak on a chromatogram as one of analysis parameters; a data point number storage () configured to store information on an appropriate number of data points corresponding to one peak; a sampling time interval calculator () configured to calculate a sampling time interval, which is a timing for acquiring data for creating the chromatogram, from the inputted peak width and data point number; and an analysis control unit () configured to control an operation of the mass spectrometer so as to acquire ion intensity data in the mass spectrometer according to the sampling time interval.
