Document Type and Number:
Japanese Patent JPWO2021095105
Kind Code:
A1
Abstract:
First product ion spectrum data is acquired by dissociating a precursor ion derived from a sample component by collision between the precursor ion and an inert gas molecule to generate product ions, and detecting the product ions after separating the product ions according to a mass-to-charge ratio; second product ion spectrum data is acquired by dissociating the precursor ion by a reaction of the precursor ion with hydrogen radicals to generate product ions, and detecting the product ions after separating the product ions according to a mass-to-charge ratio; and a set of product ions having a predetermined mass difference is extracted in the first product ion spectrum data and the second product ion spectrum data.
