  • Patent number: 9346058
    Abstract: Provided is a unit which is capable of readily grinding and collecting a small amount of a sample which is difficult to be ground. The unit for grinding a sample comprises a club-shaped pestle and a mortar into which the pestle can be inserted, wherein the pestle comprises a roughened taper located at at least one end of its pestle body, wherein the mortar is a tube with an inverted frustoconical bottom, and the surface of the mortar where the taper of the pestle contacts the inverted frustoconical bottom when the pestle is inserted into the mortar is roughened, and wherein the angle of the taper with respect to the longitudinal centerline of the pestle is substantially equal to the angle of the inner wall of the inverted frustoconical bottom with respect to the longitudinal centerline of the mortar. The roughened taper and surface improve grinding efficiency.

  • Publication number: 20160035553
    Abstract: After a sample such as a biomedical tissue section is attached to an electrically-conductive slide glass (S1), the film layer of a matrix substance is appropriately formed by vapor deposition so as to cover the sample (S2). The crystal of the matrix substance in the film layer is very fine and uniform. Subsequently, the slide glass on which the matrix film layer is formed is placed in a vaporized solvent atmosphere, and the solvent infiltrates into the matrix film layer (S3). When the solvent sufficiently infiltrated is vaporized, a substance to be measured in the sample takes in the matrix and re-crystallized. Furthermore, the matrix film layer is formed again on the surface by the vapor deposition (S4). The added matrix film layer absorbs excessive energy of a laser beam during MALDI, which suppresses the denaturation of the substance to be measured and the like, so that high detection sensitivity can be achieved while high spatial resolution is maintained.
