Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a gas chromatography-mass spectrometer, which has the advantages of dust-proof function and height adjustment function, and solves the problem that the existing gas chromatography-mass spectrometer is used in the process of testing samples. Putting it on the table, during the detection process, due to long-term storage, it is easy to accumulate dust and fluff on the surface of the detection sample, which will affect the final detection accuracy. It is very inconvenient in the process of moving and moving, resulting in a certain amount of garbage accumulated at the bottom due to long-term placement, which is difficult to clean and easy to breed bacteria. When the garbage is not cleaned in time, it is easy to affect the working environment

Abstract

The invention relates to the technical field of environmental protection, and further discloses a gas chromatograph-mass spectrometer. The spectrometer comprises a combined instrument body, a dustproof cover is arranged at the bottom of the sample detector; a door body is mounted on the surface of the dustproof cover at the slot through a hinge shaft; a limiting piece is mounted at the front end of the surface of the door body; and a clamping piece is installed on the surface of the dust cover on one side of the open groove, a clamping groove is formed in the surface of the clamping piece, a second hydraulic cylinder is installed in the combination instrument body, a fixing rod is installed at the output end of the second hydraulic cylinder through a piston rod, and supporting rods are symmetrically installed at the bottom of the fixing rod. According to the gas chromatograph-mass spectrometer, the dustproof cover, the clamping groove, the limiting block, the second hydraulic cylinderand the supporting rod are arranged, so that the gas chromatograph-mass spectrometer has a dustproof function and a height adjusting function, a detection sample is convenient to replace, pollution isreduced, dust is prevented from being left on the gas chromatograph-mass spectrometer to influence the precision of the gas chromatograph-mass spectrometer, and meanwhile, bacteria breeding caused bylong-term accumulation of garbage is avoided.
