Abstract: A sample support body is a sample support body used for ionizing components of a sample. The sample support body includes a substrate, a conductive layer, and a plurality of particles. The substrate includes a main surface and a plurality of holes opened in the main surface. The conductive layer is provided on the main surface so that the holes are not blocked. The plurality of particles are provided on a surface of the conductive layer. The absorption rate of the plurality of particles with respect to the energy beam used for ionization is equal to or higher than the absorption rate of the conductive layer with respect to the energy beam.

Abstract: A sample support unit includes a substrate having a first surface and a second surface, and having a porous structure formed therein and opened to at least the first surface, and a frame removably attached to the substrate and retaining the substrate such that at least a part of the first surface is exposed. The frame has a fixing portion positioned outside the substrate when viewed in a direction perpendicular to the first surface, in the state of being attached to the substrate.

Abstract: A sample support includes a substrate including a first surface, and a second surface on a side opposite to the first surface, and including a measurement region in which a porous structure for communicating the first surface and the second surface with each other is formed. A calibration portion including a surface flush with the first surface is formed in the substrate. The water absorbability of the calibration portion is lower than the water absorbability of the measurement region.
