Title:
LASER DESORPTION/IONIZATION METHOD AND MASS SPECTROMETRY METHOD
Document Type and Number:
WIPO Patent Application WO/2019/106962
Kind Code:
A1
Abstract:
This laser desorption/ionization method involves: a first step in which a sample support body (1) is prepared which comprises a substrate (2) in which multiple through-holes are formed that open in a first surface (2a) and a second surface (2b) opposite each other, and a conductive layer which is provided on at least a first surface; a second step in which the sample (S) and a solvent (81) having low volatility in a vacuum is introduced into the multiple through holes; and a third step in which a component of the sample is ionized by irradiating the first surface with laser light while applying a voltage to the conductive layer.
