Abstract

The invention discloses a top entry type polar coordinate adjusting device used for a desorption atmospheric pressure chemical ionization source. The adjusting device comprises an installation connector, a Y-direction horizontal-movement adjusting module, a Z-direction horizontal-movement adjusting module, an A-axis angle adjusting module, an ion source nozzle, an integrated connector, a sample introduction Z-direction automatic adjusting module, a sample introduction X-direction automatic feeding module and a sample introduction Y-direction manual adjusting module. The adjusting device can accurately and quantitatively adjust the angle alpha between the ion source nozzle and a mass spectrometer sample inlet, the Z-direction distance a1 between the ion source nozzle and the mass spectrometer sample inlet, the Y-direction distance b1 between the ion source nozzle and the mass spectrometer sample inlet, the Z-direction distance a2 between a sample table and the mass spectrometer sample inlet and the Y-direction distance b2 between the sample table and the mass spectrometer sample inlet. The adjusting device is applicable to researching and optimal configuration of the relation between the signal intensity and space position parameters among the ion source nozzle, the sample table and the mass spectrometer sample inlet, and is particularly applicable to rapidly detecting solid samples in batch and carrying out imaging mass spectrometry on continuously-distributed samples.
