Title: Method of manufacturing specimens of poorly water-soluble materials for maldi mass spectrometry and sample plate used in the method
Inventor: YONGJIN BAE
IPC: H01J49/16
Filed: 2019-12-06
Abstract: The present invention relates to a method for preparing a specimen with uniform thickness of homogeneous, low water-soluble material sample by using a sample plate including a substrate and a plurality of protrusions disposed on the top of the substrate, wherein the protrusion has a planar surface to endure force when the upper part is pressurized, and to a method for quantitative analysis of a low water-soluble material by performing matrix assisted laser desorption/ionization (MALDI) mass spectrometry on the specimen. In accordance with the present invention, when the sample plate having protrusions is used along with a pellet cup in preparing a specimen of a low water-soluble material for MALDI mass spectrometry, the portion where the sample is introduced is made mainly pressurized as the pellet cup containing the sample placed on the protrusion is pressurized, thereby preventing the pellet cup from being crumpled to crush the edge of the specimen when pressurized and avoiding exfoliation of the specimen from the sample plate. In addition, bending of the sample plate can be prevented to allow the sample plate to be reused, thereby enhancing reproducibility of specimen preparation. Therefore, a homogeneous, low water-soluble material specimen with a small deviation in thickness can be prepared and easily reproducible. A MALDI spectrum can be obtained from the specimen, thereby enabling a user to use a commercial MALDI-TOF MS instrument to analyze a low water-soluble material quantitatively.
