When a product ion corresponding to a precursor ion set for a sample is selected by performing product ion scan with respect to the precursor ion, an exclusion range of mass-to-charge ratios is set based on information on non-selection ions input by a user, and a product ion that satisfies a predefined criterion is selected within a range of mass-to-charge ratios excluding the exclusion range in a product ion spectrum. According to the mass spectrometric method of the invention, product ions suited for measurement on a target compound can be selected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mass spectrometric method, mass spectrometer, and mass spectrometric data processing program","description":"In a mass spectrometric method of the invention, a mass spectrometer (2) is used having a mass separation unit (231, 234) before and after a collision cell (232) for fragmenting ions.
