Data processing method and device based on triple quadrupole mass spectrometer

Abstract

The invention discloses a data processing method and device based on a triple quadrupole mass spectrometer. The device comprises a signal conditioning circuit module and an FPGA chip. According to the data processing device based on the triple quadrupole mass spectrometer, when the device is used for a long time, internal electronic devices can generate heat, the change of heat enables an elliptical air bag to deform, the deformation of the elliptical air bag can press a rotating straight rod to drive a limiting ball to move along the interior of an arc-shaped elastic pipe, and under the action of the movement of the limiting ball, the arc-shaped elastic pipe can rotate; the arc-shaped elastic pipes can be deformed, the movable balls can be pushed to move out of the heat dissipation holes, the heat dissipation holes are exposed to achieve exchange of internal and external gas, and therefore the purpose of heat dissipation is achieved, and due to the arrangement, when the device is not used, the heat dissipation holes are in a closed state, external dust is prevented from entering the device along with the gas, and the service life of the device is prolonged. Therefore, the use of the device is influenced.

Description

technical field [0001] The invention relates to the technical field of mass spectrometer equipment, in particular to a data processing method and device based on a triple quadrupole mass spectrometer. Background technique [0002] The structure of the existing mass spectrometer includes: a sampling system, an ion source, a vacuum system, a mass analyzer, and a detector. Mass analyzer is the core component of mass spectrometer for molecular ion fragmentation and screening. The types can be divided into sector magnetic field mass spectrometer, quadrupole mass spectrometer, ion trap mass spectrometer, time-of-flight mass spectrometer, Fourier transform mass spectrometer and orbit trap. mass spectrometer, etc. The triple quadrupole mass analyzer consists of two front and rear quadrupoles and a collision reaction cell sandwiched between them. Since the early collision cells were also composed of quadrupoles, the mass spectrometer with this mass analyzer is called triple quadrup...

AI Technical Summary

Problems solved by technology

[0004] The existing data processor needs to work for a long time for data processing, and the long time work will increase the internal temperature. In the prior art, the heat dissipation of the data processor is generally provided with cooling holes on the outer wall, so that not only heat dissipation The effect is not good, and when the data processor is working normally, the external dust will enter the data processor through the cooling holes along with the air, thus affecting the use of the data processor
