A sample support body is used for ionizing a component of a sample. The sample support body includes: a substrate; a porous layer provided on the substrate and having a front surface on a side opposite to the substrate; and a partition portion partitioning the front surface into a first region and a second region. The porous layer includes a main body layer having a plurality of holes opening to the front surface. The partition portion includes a partition groove formed on the front surface so as to pass between the first region and the second region.

Sample support body, ionization method, and mass spectrometry method

A sample support body includes: an insulating substrate having a measurement region formed with a plurality of through holes; a frame formed with an opening part opening to a first face and a second face to correspond to the measurement region, and formed on the first surface such that the opening part overlaps the measurement region when viewed from a thickness direction of the substrate; an adhesive layer to bond the substrate and the frame and having a protruding portion protruding from an inner surface of the opening part toward the measurement region; and a conductive layer having a first portion provided along the inner surface of the opening part, a second portion provided along the first surface of the measurement region, and a third portion provided along a surface of the protruding portion so as to connect the first portion and the second portion.

Specimen carrier and method for manufacturing specimen carrier

A sample support is used for ionization of a sample. The sample support includes a film part having a first front surface and a first back surface, the film part being formed with a plurality of through-holes, and a support part defining a measurement region for ionizing the sample with respect to the film part and supporting the film part. The support part includes an inner portion having a second front surface and a second back surface, the film part being fixed to the inner portion, and an outer portion having a third front surface and a third back surface and extending along an outer edge of the inner portion. A difference generated between a position of the first front surface and a position of the third front surface in a thickness direction of the film part is smaller than a thickness of the film part.

Sample support, adapter, ionization method and mass spectrometry method

A sample support includes: a substrate having a plurality of through-holes opening on a first surface and on a second surface; a first member having a plurality of first openings and disposed on the first surface; a second member having a plurality of second openings and disposed on the second surface, and; a bonding member disposed between the first member and the second member; and a conductive layer integrally provided on a region of the second surface corresponding to each of the plurality of second openings. The plurality of through-holes include a plurality of first through-holes located between each of the plurality of first openings and each of the plurality of second openings, and a plurality of second through-holes located between the first member and the second member. Each of the plurality of second openings communicate with each of the plurality of first openings through the plurality of first through-holes.

Sample support

A sample support body for ionization of a sample, including: a substrate having a first surface, a second surface on a side opposite to the first surface, and a plurality of through-holes opening on each of the first surface and the second surface; a conductive layer provided on the first surface; and a matrix crystal layer provided on at least one of the conductive layer and the second surface, in which the matrix crystal layer is formed of a plurality of matrix crystal grains so as to include a gap communicating the plurality of through-holes with an outside.
