Abstract

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 mechanism is used to conveniently complete the sampling of different agents; manual disassembly and assembly of a conveying pipeline are not needed; and the operation is simplified.

Description

technical field [0001] The invention relates to the field of experimental instruments, in particular to a mass spectrometer sampling device. Background technique [0002] A mass spectrometer is a common experimental instrument, also known as a mass spectrometer. An instrument for separating and detecting different isotopes. That is, according to the principle that charged particles can be deflected in an electromagnetic field, a type of instrument is used to separate and detect material composition according to the mass difference of material atoms, molecules or molecular fragments. [0003] Sampling devices are required in the process of testing samples. At present, the sampling devices of mass spectrometers need to manually disassemble and assemble the delivery pipeline when sampling different samples. Contents of the invention [0004] The object of the present invention is to provide a mass spectrometer sampling device to solve the above problems. [0005] To achiev...
