Title:
Mass spectrometry method, chromatograph mass spectrometer, and mass spectrometry program
Document Type and Number:
Japanese Patent JP6288313
Kind Code:
B2
Abstract:
A mass spectrometry method includes: creating a plurality of measurement conditions corresponding to all combinations of precursor-ion candidates generated from the target compound and collision-energy-value candidates; performing a product-ion scan measurement using each of the plurality of measurement conditions and performing a plurality of reference measurements for detecting a predetermined kind of ion generated from the target compound under the same condition, within an introduction time during which the target compound is introduced; creating a peak function, which is a function representing a change in the amount of introduction of the target compound into the mass spectrometer within the introduction time, based on the result of the reference measurement; creating a normalization function for normalizing the amount of introduction of the target compound within the introduction time, based on the peak function; and normalizing the intensity of product-ion spectra obtained by the product-ion scan measurements performed for all combinations.
