Mass spectrometer experiment table with shockproof and noise-reduction functions

Abstract

The invention discloses a mass spectrometer experiment table with shockproof and noise-reduction functions. The mass spectrometer experiment table comprises a stainless steel table top, a stainless steel support and a mechanical pump storage room, wherein the stainless steel support supports the stainless steel table top, and the mechanical pump storage room is positioned at the lower part of the stainless steel bench top; a bottom wall is arranged at the mechanical pump storage room, a rubber blanket is arranged at the upper part of the bottom wall, and the inner part of the rubber blanket is lined with a wavy sponge; the thickness of the stainless steel table top is more than 16 mm. In the working process of a mass spectrometer, the mass spectrometer is placed on the stainless steel table top, and the stainless steel table top with the thickness of more than 16 mm has sufficient rigidity; a mechanical pump used for providing a vacuum degree is placed in the mechanical pump storage room; as the rubber blanket is arranged on the bottom wall of the mechanical pump storage room and the inner part of the rubber blanket is lined with the wavy sponge, the influence of the vibration of the mechanical pump on the mass spectrometer can be minimized, the harm to operators caused by high-decibel noise caused by vibration are reduced, the instrument maintenance is convenient, and meanwhile the analytical sensitivity and accuracy of the mass spectrometer can be ensured.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for detection and analysis equipment, in particular to a mass spectrometer test bench with anti-vibration and noise-reducing functions. Background technique [0002] Tandem liquid chromatography-mass spectrometry (LC-MS / MS) separation and detection technology has developed extremely rapidly in recent years. The use of LC / MS technology began in the 1970s. Since the 1990s, due to the successful application of atmospheric pressure ionization and the development of mass spectrometers, the combination of liquid phase and tandem mass spectrometry (MS / MS) has received great attention and develop. It has been widely used in life science, environmental science, forensic science, commodity inspection and other fields. [0003] The vacuum system is an important part of the mass spectrometer. The vacuum system works continuously through an external mechanical pump to ensure the high vacuum degree in...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no experimental bench suitable for mass spectrometers in the industry. Generally, mechanical pumps and mass spectrometers are directly placed on ordinary experimental benches or ordinary instrument benches. When the mechanical pump is working, it will generate high-decibel noise due to vibration, which is very difficult for experimenters. Cause greater damage; at the same time, vibration will also affect the analytical sensitivity and accuracy of the mass spectrometer
