METHOD FOR IMAGING MASS ANALYSIS USING PHYSICAL VAPOR DEPOSITION OF PLATINUM NANOPARTICLES

摘要

The present invention provides an improved method for imaging mass spectrometry using an ionization-assisting matrix of a test sample, wherein the ionization efficiency is high, migration and visual information reduction are inhibited, no interference peaks originating from the matrix occur, and the analysis can be performed at high spatial resolution.;Specifically, the present invention provides a method for imaging mass spectrometry using a sample prepared by physical vapor depositing platinum nanoparticles on the surface of a test sample to be subjected to imaging mass spectrometry.
