Title:
SUBSTRATE FOR MASS SPECTROMETRIC ANALYSIS, PROCESS FOR PRODUCING SAME, AND MASS SPECTROMETRY
Document Type and Number:
WIPO Patent Application WO/2011/004889
Kind Code:
A1
Abstract:
A substrate for mass spectrometric analysis is provided with which it is possible to further advance the performance of a matrix-free ionization method and to conduct analysis by laser desorption ionization-mass spectrometry without requiring the use of an ionizing agent which can be causative of noise or a decrease in detection sensitivity. Also provided is a process for producing the substrate. The substrate for mass spectrometric analysis comprises a base equipped thereon with a metal oxide to which an organic substance capable of supplying protons and/or cations is adherent. The process for producing the substrate for mass spectrometric analysis comprises: coating a base with a metal oxide dispersion obtained by dispersing a metal oxide with the aid of an organic substance capable of supplying protons and/or cations; and drying the coating.
