A sample plate in use with a MALDI-TOF (matrix-assisted laser desorption ionization time-of-flight) mass spectrometer. The sample plate is usable for the mass spectrometry of a polymeric material on the order of several hundreds of Da and a method of manufacturing the same sample plate. The sample plate including a target plate, an organic matrix formed on one surface of the target plate, and a Parylene thin film formed on the target plate on which the organic matrix is formed, the Parylene thin film entirely covering the organic matrix.

Sample plate using MALDI-TOF mass spectrometer and manufacturing method of the sample plate

The present invention relates to a sample plate to be used for a MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time of Flight) mass spectrometer, and more particularly, to a sample plate for a MALDI-TOF mass spectrometer, which is particularly useful for molecular weight measurement of a high-volatile material, a method of manufacturing the sample plate and a mass spectrometry method using the sample plate. Object of the present invention to provide a method capable of performing a mass spectrometry for a high-volatile material by using a MALDI-TOF mass spectrometer so as to overcome the limits of the gas chromatography method of the related art. According to the present invention, there is provided a sample plate including a target plate, an organic matrix formed on one surface of the target plate, a parylene thin film formed on the target plate having the organic matrix formed thereon and formed to cover the entire organic matrix, and a sample fixing layer formed on the parylene thin film. The sample fixing layer is made of at least one material selected from a group consisting of graphene and carbon nano tube (CNT).
