CHIP FOR MASS SPECTROMETRY, AND LASER DESORPTION IONIZATION-TIME OF FLIGHT MASS SPECTROMETER AND MASS SPECTROMETRY SYSTEM USING SAME

摘要

A hole (103) is formed in a substrate (101) by etching or the like. A sample solution is dripped into the hole (103), and a dried sample is obtained. The as-obtained dried sample is subjected to LDI-TOFMS measurement together with the substrate (101).
