Abstract
The invention provides an axial acceleration collision pool. The axial acceleration collision pool comprises an outer wall and a power supply and further comprises six electrode poles, wherein the six electrode poles are symmetrically arranged in a space in the outer wall and encircle a space with gradually-reducing inner diameter. The axial acceleration collision pool has the advantages of good acceleration effect and the like, and is simple to assemble.
Description
Technical field
The present invention relates to mass spectral analysis, particularly axially accelerate collision pond.
Background technology
Triple quadrupole bar tandem mass spectrometer is when carrying out multiple channel test, if the daughter ion of previous passage can not discharge collision in time, pond just may have an impact to the signal of next passage, cause false-positive result, impact quantitatively and qualitatively result, this phenomenon is called collision pond cross talk effects.
The collision pond of the current triple quadrupole mass spectrometer technology axially accelerated that adopts is accelerated daughter ion more, makes daughter ion accelerate to leave collision pond, avoids cross talk effects.Axially accelerate to realize mainly through following several mode:
1. using surface to scribble the Metallic rod of resistance material, forming potential gradient along pole direction, so just can accelerate ion after applying voltage.This mode requires higher to processing technology
2. adopt the Metallic rod of special shape to form gradient potential in the Ion paths of collision pond, such as, adopting the Metallic rod that thick one end, one end is thin, by loading different voltage on pole, potential gradient can be realized on axis.This mode requires higher to the processing technology of pole and mounting process
3. use the Metallic rod of normal shape, as cylindrical, but pole is installed with certain angular slope, after Metallic rod on-load voltage, gradient voltage can be formed in Ion paths.This mode requires higher to mounting process.
Summary of the invention
In order to solve the deficiency in above-mentioned prior art, the invention provides and a kind ofly assemble simple, that acceleration effect is good axis and accelerate collision pond.
The object of the invention is to be achieved through the following technical solutions:
