Description

Technical Field

[0001] The utility model relates to the technical field of mass spectrometers, in particular to a mass spectrometer device with adjustable angle. Background Art

[0002] The mass spectrometer needs to ionize the sample when working. Since the target plate containing the sample must be placed directly under the flight tube and there cannot be any obstruction on the transmission path, the laser must be a certain distance away from the target plate in the horizontal direction, resulting in a certain angle between the laser and the normal of the target plate. When ions are excited, it is biased excitation. The ion beam moves along the reflection path of the laser and cannot fly vertically to the flight tube, which is not conducive to the flight of ions after ion excitation. The ionization efficiency and resolution are not ideal. Therefore, the angle of the mass spectrometer needs to be adjusted to align the laser with the target plate.
