SAMPLE SUPPORT, METHOD FOR PRODUCING SAMPLE SUPPORT, AND METHOD FOR IONIZING SAMPLE

摘要

The sample support includes a substrate having a first surface and a second surface facing each other, and a conductive layer provided on at least the first surface. The substrate and the conductive layer are formed with a plurality of through holes that open to the third surface and the second surface opposite to the substrate of the conductive layer. At least one of the second surface and the third surface is subjected to a surface treatment for making the affinity for water different between the second surface side surface and the third surface side surface.
