Mass analysis method, mass spectrometer, and mass spectrometric data processing program

摘要

In the mass spectrometry method of the present invention, a mass spectrometer (2) having mass separation units (231) and (234) is used in front of and behind a collision cell (232) that cleaves ions. When product ions corresponding to the precursor ion are selected by conducting product ion scanning on the precursor ions set for the sample, excluding the mass-to-charge ratio based on the information on the non-selected ions input by the user A range is set and product ions satisfying a predetermined criterion are selected from the product ion spectrum within the range of the mass to charge ratio excluding the exclusion range. According to the mass spectrometry method of the present invention, it is possible to select product ions suitable for measurement of a target compound.
