| Outline of Final Research Achievements |
We have shown that breakdown diagrams obtained by energy-resolved tandem mass spectrometry (ER-MS/MS) experiments are useful for identification of small organic molecules and differentiation of isomers including diastereomers, such as Thr and allo-Thr, as well. The established ER-MS/MS method is based on intentional observation of energy dependence in fragmentation chemistries and fast and sensitive enough to be used in the context of omics molecular identification. Our strategy would leads to an innovation in molecular identification in future omics sciences where isomer differentiation will become an even bigger challenge under mass imaging, single cell analysis, and/or ambient in situ ionization setups where no chromatography is available.
