Mass spectrometer sampling device

The invention discloses a mass spectrometer sampling device, and relates to the field of testing instruments. The sampling device comprises a workbench, a base and a mounting base. A sampling pump isarranged on the mounting base. The input end and the output end of the sampling pump are connected with a liquid pumping pipe and a liquid supply pipe respectively. The workbench is rotatably connected with the base through a rotating shaft. The base is provided with a driving mechanism which drives the workbench to rotate. A number of placement grooves are equidistantly at the top of the workbench along the circumferential direction. Sample bottles are arranged in the placement grooves. Vertical sampling pipes are inserted into the sample bottles. When the sampling pipes are rotated below themounting base, the liquid pumping pipe is communicated with the sampling pipes through a conduction mechanism. According to the invention, the rotating workbench and the fixed mounting base are arranged; the conduction mechan
