Mass analysis data processing apparatus and mass spectrometric data processing method

摘要

To enhance the efficiency in the operation of checking a plurality of mass spectra acquired by measuring MSn (n is an integer equal to or more than two) of a sample containing an unidentified component under a plurality of measurement conditions. A mass analysis data processing apparatus for processing data constituting a plurality of mass spectra acquired by performing MSn (n is an integer equal to or more than two) measurement of an unidentified component contained in a sample under a plurality of different measurement conditions, the apparatus including: a determination condition input unit 43 for allowing an analyst to input a determination condition concerning a maximum intensity value of mass peaks on the mass spectra, in order to select, out of the plurality of mass spectra, a mass spectrum or mass spectra effective for presuming the unidentified component; a determination execution unit 44 for determining whether or not the determination condition is satisfied in each of the plurality of mass spectra; and a selection result presentation unit 45 for selecting a mass spectrum or mass spectra, determined to satisfy the determination condition by the determination execution unit 44, and presenting the mass spectrum or spectra to the analyst.
