Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention discloses a sample target lifting mechanism, a mass spectrometer sample changing device and a mass spectrometer sample changing method. The sample target lifting mechanism comprises a lifting seat, a lifting platform, a first sleeve shaft, a first linkage rod, a second linkage rod and a third linkage rod, one end of the first linkage rod is rotatably connected with the lifting table,and the other end of the first linkage rod is rotatably connected with the lifting seat; one end of the second linkage rod is rotationally connected to the lifting table, and the other end of the second linkage rod is rotationally connected with the lifting seat. The third linkage rod is rotatably connected with the second linkage rod, the third linkage rod is further rotatably connected with a first sleeve shaft, one end of the elastic component is connected with the lifting seat, and the other end of the elastic component is connected with the second linkage rod; the first sleeve shaft is used for being matched with an external driving assembly. The mass spectrometer sample changing device comprises the sample target lifting mechanism. The sample target lifting mechanism is low in cost,compact in structure and small in occupied space.

Description

technical field [0001] The invention relates to the field of mass spectrometry detection, in particular to a sample target lifting mechanism, a mass spectrometer sample changing device and a mass spectrometer sample changing method. Background technique [0002] Matrix assisted laser desorption ionization time-of-flight mass spectrometer is a biological mass spectrometer commonly used in the analysis of macromolecular samples. Transported to the ionization zone under vacuum for ionization analysis. Since the sample cannot enter the vacuum environment directly from the normal pressure, the sample injection chamber must ensure that the sample can be gradually transformed from the normal pressure environment to the vacuum state, so as not to affect the vacuum parameters of the instrument and ensure the analysis results. The traditional method is to set up a sampling hole on the cavity wall of the sampling chamber. There is a lifting device for lifting the sample target in the ...
