Title: SURFACE-ASSISTED LASER DESORPTION/IONIZATION METHOD, MASS SPECTROMETRY METHOD AND MASS SPECTROMETRY DEVICE
Abstract:
A surface-assisted laser desorption/ionization method according to one aspect of the present invention includes: a first step of preparing a sample supporting body 2 provided with a base plate 21 having a plurality of through-holes S which penetrate through from one surface 21a to another surface 21b, and an electrically conductive layer 23 covering at least the one surface 21a; a second step of placing a sample 10 on a sample stage 1 and disposing the sample supporting body 2 on the sample 10 in such a way that the other surface 21b opposes the sample 10; and a third step of irradiating the one surface 21a with a laser L to ionize the sample 10 which has migrated through the through-holes S by means of capillary action from the other surface 21b side to the one surface 21a side.
