Method of identifying substances using mass spectrometry |
摘要 |
An object of the present invention is to provide a mass spectrometry system capable of improving an efficiency of obtaining information on a structure of substances, shortening a time taken for a measurement and substance identification, and improving identification accuracy. The system comprises: a process of mass analyzing an ionized analyte; a first fragmentation process where a first ion is selected from the ions observed in a mass spectrometry to fragment it; a process of mass analyzing a plurality of the ions generated in the first fragmentation process; a process of determining fragment ion combination capable of reconstructing the first ion using a result of the mass spectrometry; a second fragmentation process where the fragment ions contained in the fragment ion combination are fragmented; and a process of mass analyzing the fragment ions generated in the second fragmentation.
