Title: MASS SPECTROMETRY DEVICE AND MASS SPECTROMETRY METHOD
Abstract:
A mass spectrometry device 200 according to one aspect of the present invention is provided with: a sample supporting body 2 provided with a base plate 21 on which a sample 10 is placed and which is provided with a plurality of through-holes S penetrating from one surface 21a to another surface 21b, and an electrically conductive layer 23 covering at least a part of the one surface 21a in which the through-holes S are not provided; a sample stage 1 configured in such a way that the sample supporting body 2 is placed thereon in such a way that the other surface 21b faces the sample 10; a laser radiating unit 201 which controls radiation of a laser L in such a way that the laser L is radiated onto an imaging target region R1 of the one surface 21a; and a detector 203 which detects the sample 10 that has been ionized by means of the laser L radiation, in a state in which a positional relationship of the sample 10 in the imaging target region R1 is maintained.
