Description

technical field [0001] The invention relates to the field of matrix-assisted laser analysis ion source laser and imaging, in particular to an integrated system of matrix-assisted laser analysis ion source laser and imaging. Background technique [0002] A matrix-assisted laser desorption ion source is a device that can realize the process of decomposing a solid-state sample to be analyzed. The sample to be analyzed forms a solid state under normal pressure, which is made into a target sample and loaded into the vacuum system through the target mechanism. The analyzed protons are solidified on the target stage, the laser system and the CCD imaging system are fixed on the lens cavity system, and the central axes of the two are symmetrically distributed at a certain angle with respect to the central axis of the focus position of the target stage. The light of a certain wavelength is emitted through the laser system, and it is transmitted on the sample target through the optica...
