MATRIX AGENT FOR MASS SPECTROMETRY, MASS SPECTROMETRY METHOD, AND MASS SPECTROMETRY IMAGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a matrix agent and mass spectrometry method that are applicable to mass spectrometry using a matrix and can accurately perform the mass spectrometry.;SOLUTION: The matrix agent for mass spectrometry includes nano fine particles each having a core made of MFe₂O₄ (M shows transition metal in MFe₂O₄) and a shell made of amorphous SiO₂ for covering the core. The mass spectrometry method includes: a process of applying laser irradiation to the matrix agent and an analysis sample containing an analysis object and supporting the ionization of the analysis sample; and a process of acquiring mass spectrometry data of the analysis object.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
