Sample mounting plate
A sample mounting plate has: a substrate made of alumina ceramic which exhibits white; and a cover layer which is laminated so as to cover the front surface of the substrate and which has multiple grooves formed in some areas. The cover layer has: a conductive interference layer which exhibits conductivity and is configured so as to exhibit a prescribed color (such as navy blue) through light interference and which is laminated on the substrate; and a water-repellent layer which exhibits higher water repellency than that of the substrate and is laminated on at least a part of the conductive interference layer and on which a sample is to be mounted.
1. A sample mounting plate comprising:
a substrate that has an insulation property;
a conductive interference layer that has conductivity and exhibits a color different from the substrate with optical interference, and is laminated on the substrate; and
a water-repellent layer that has water repellency higher than water repellency of the substrate, and is laminated on at least part of the conductive interference layer,
wherein a sample to become an object of ionization in mass spectrometry is mounted on at least one of the conductive interference layer and the water-repellent layer.
