Title:
レーザ脱離イオン化法及び質量分析方法
Document Type and Number:
Japanese Patent JP6899295
Kind Code:
B2
Abstract:
A laser desorption/ionization method, includes: a first step of preparing a sample support body including a substrate on which plurality of through holes opening to a first surface and a second surface facing each other are formed, and a conductive layer provided on at least the first surface; a second step of mounting a sample on a mounting surface of a mounting portion, and of disposing the sample support body on the sample such that the second surface is in contact with the sample; a third step of introducing a matrix solution into the plurality of through holes; and a fourth step of ionizing a component of the sample that is mixed with the matrix solution and is moved to the first surface side from the second surface side through the through hole by irradiating the first surface with laser light while a voltage is applied to the conductive layer, in a state where the sample is disposed between the mounting portion and the sample support body.
