Embodiment 1
[0035]figure 1 Structure of multi-mode mass spectrometry systems, such asfigure 1 As shown, the multi-mode mass spectrometry includes:
[0036]The first ion source 21, the second ion source 22 (e.g., the EI source or CI source) and the multi-stage transmission rod, the multi-stage transmission rod is disposed in a plurality of vacuum chambers in series; the first ion source 21 is atmospheric pressure ion Source, such as an ESI source or APCI source, the exit ion sequentially passes through the first vacuum chamber 12, the second vacuum chamber 13, the second ion source 22 is disposed in the vacuum chamber; the first vacuum chamber 12 and the second vacuum chamber 13 There is a spacer 61 having a first through hole 62 adapted to the ion;
[0037]Such asfigure 2 As shown, the container 91, the container 91 is isolated by the first slider 94 as the first portion 92 and the second portion 93, the first portion 92, in communication, the second truse chamber 13, the second portion 93 communicat...
Embodiment 2
[0056]Application examples of multi-mode mass spectrometry analysis systems and methods according to Embodiment 1 of the present invention.
[0057]In this application example, ifFigure 1-2As shown, the multi-mode mass spectrometry system includes four tandem vacuum chambers, and the three-stage transmission rod is disposed in the first three vacuum chambers (first to third vacuum chains), and the mass analyzer 51 is disposed in the fourth vacuum chamber 15. Inside; there is a spacer between the adjacent vacuum chambers, the spacer has a through hole suitable for ions; wherein the first spacer 61 having the first vacuum chamber 12 and the second vacuum chamber 13 has a first through hole 62. The first ion source 21 employs an ESI source, disposed within the atmospheric pressure ionization chamber 11; the second ion source 22 is provided in the third vacuum chamber 14, and is in the side of the transmission rod 43; ion deflection module setting In the third vacuum chamber 14, the ions e...
Embodiment 3
[0068]According to an application example of a multi-mode mass spectrometry system and method according to Embodiment 1 of the present invention, it is different from Example 1:
[0069]A guide or guide is provided on the first spacer, the second slider moving on the guide or rail, so that the second slider is moving up and down, and the left and right are not missing, and the second pass is guaranteed. Correspondence and communication between the holes and the first through hole.
[0070]The spring is disposed on the upper side of the second slider, and when the second slider moves upward, the spring is compressed, producing a downward elastic force, that is, spring hinders the second slider.
