The present invention relates to a sample plate for MALDI mass spectrometry and a method of manufacturing the sample plate, the sample plate comprising a metal plate; And a thin film coated on the surface of the metal plate and loaded with a sample to be analyzed, wherein the thin film is formed of at least one inorganic material selected from the group consisting of oxides, nitrides, and non-sulfides, and is heat-treated separately after coating the surface of the metal plate. It is characterized by. According to the present invention, precise analysis of a low molecular weight sample can be effectively performed without using a general organic acid matrix, and the molecular weight region of the analyte can be extended to a high molecular weight region (5000 Da). |
