Problems solved by technology

It can be seen that the mass analysis method of the traditional tandem mass spectrometry equipment is still a single time-of-flight mass analysis, the journey of ions from generation to detection is relatively long, the probability of ion loss is high, and high resolution and high ion utilization cannot be considered at the same time. requirements
[0004] Therefore, traditional tandem mass spectrometry equipment has the disadvantage of limited application scenarios

Abstract

The invention relates to tandem mass spectrometry equipment and a mass spectrometry detection system. The mass spectrometry equipment comprises a focusing device, a time-of-flight mass analyzer, an ion trap mass analyzer and a control device. The focusing device is used for focusing to-be-measured ions, so that the to-be-measured ions reach the post-stage time-of-flight mass analyzer. The control device is used for adjusting the moving trajectory of the to-be-tested ions according to test requirements, and realizing the working mode switching of time-of-flight mass spectrometry or ion trap mass spectrometry. The time-of-flight mass analyzer is used for performing time-of-flight mass spectrometry on the to-be-detected ions when the working mode is the time-of-flight mass spectrometry. The ion trap mass analyzer is used for performing ion trap mass spectrometry on the to-be-detected ions passing through the time-of-flight mass analyzer when the working mode is the ion trap mass spectrometry. The application scenes of the tandem mass spectrum equipment can be expanded.

Description

technical field [0001] The present application relates to the technical field of mass spectrometry detection, in particular to a tandem mass spectrometry device and a mass spectrometry detection system. Background technique [0002] The mass spectrometry method is to ionize material particles into ions, and separate them according to the spatial position and time sequence through an appropriate stable or changing electric field or magnetic field to achieve mass-to-nuclear ratio separation, and detect its intensity for qualitative and quantitative analysis. . The tandem analysis method, which is one of the methods of mass spectrometry, has been widely used in various fields in recent years. [0003] The traditional tandem mass spectrometry equipment, the front-stage ion trap of the time-of-flight mass spectrometer is combined to obtain the ion trap time-of-flight mass spectrometer (Ion Trap-Time of Fight Mass Spectrometer, IT-TOFMS), in which the ion trap is used to select a...
