Description
Technical field
The present invention relates to a kind of quadrupole rod, relate in particular to a kind of grid type static quadrupole rods device.
Background technology
Static quadrupole rod is a kind of conventional ion transfer device in mass spectrometer, and its effect is to coordinate with front and back electrode to form a traction constraint electric field, controls direction and the shape of ion beam, thereby improves the efficiency of transmission of ion.
But conventional static structure of quadrupole is made up of one group of ganoid stainless steel substrates now, has executed DC voltage on bar, polarity of voltage is positive and negative all can. Between adjacent stems, leave certain interval as bleeding point, to ensure the vacuum of static quadrupole rods device inside, avoid vacuum too low. For preventing penetration of electric field, regulate sample ions bundle according to specific direction outgoing static quadrupole rod, need to require between bar gap as far as possible little; But due to the vacuum requirement of static quadrupole rod inside, expect that again large as far as possible bar gap is as gas outlet. Therefore, this kind of structure is difficult to meet the demand of vacuum and current field condition simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the object of this invention is to provide one simple in structure, can meet a kind of grid type static quadrupole rods device of vacuum and current field condition simultaneously.
The technical solution adopted in the present invention is:
A kind of grid type static quadrupole rods device, comprise four utmost point bars and two pole plates, described four utmost point bars are located between two pole plates, four described utmost point bars are uniformly distributed setting and surround formation cavity, described pole plate is provided with aperture, between two adjacent utmost point bars, leave spacing, described utmost point bar is provided with through hole, and described through hole is coated with aperture plate.
Be further used as preferred embodiment, on described utmost point bar and be provided with the sawtooth of equidistant arrangement near the two ends of pole plate.
Be further used as preferred embodiment, described through hole be shaped as rectangle.
Be further used as preferred embodiment, the cross section of described utmost point bar is circular arc.
Be further used as preferred embodiment, described utmost point bar is stainless steel substrates.
Be further used as preferred embodiment, described aperture plate adopts metal material to process.
The invention has the beneficial effects as follows:
A kind of grid type static of the present invention quadrupole rods device is simple in structure, is setting up after aperture plate, in ensureing internal electric field, can effectively increase the speed of bleeding, improve gas flow rate, make it possible to outside neutral molecule withdrawing device as much as possible, thus the vacuum of guarantee inside of the present invention. And the present invention can not only make sample ions efficiency of transmission be improved, can also reduce ion energy and disperse, contribute to the lifting of instrumental sensitivity and resolution ratio.
Brief description of the drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
Fig. 1 is the structural representation of a kind of grid type static of the present invention quadrupole rods device;
Fig. 2 is the side schematic view of a kind of grid type static of the present invention quadrupole rods device;
Fig. 3 is the utmost point bar structural representation of a kind of grid type static of the present invention quadrupole rods device.
Detailed description of the invention
With reference to figure 1-3, a kind of grid type static of the present invention quadrupole rods device, comprise four utmost point bars 1 and two pole plates 2, described four utmost point bars 1 are located between two pole plates 2, four described utmost point bars 1 are uniformly distributed and arrange and surround formation cavity, and described pole plate 2 is provided with between 21, two adjacent utmost point bars 1 of aperture and leaves spacing, described utmost point bar 1 is provided with through hole 11, and described through hole 11 is coated with aperture plate 3.
Wherein, described four utmost point bars 1 are along the circumferential direction uniformly distributed and arrange and surround formation cavity, and the through hole 11 at utmost point bar 1 middle part, should be in large as far as possible as gas outlet, ensures that deformation does not occur structure. The winding area of aperture plate 3 will cover through hole 11, the surface potential face of utmost point bar 1 is provided by aperture plate face, the spacing of aperture plate 3 is unsuitable excessive, more can not be overstocked, suitably leave spacing, with assurance device internal electric field and reduce electric field in through hole 11 places infiltrations, can't affect the performance of through hole 11 as device gas outlet. Ensureing, under the condition that consecutive roots bar 1 insulate, to dwindle as far as possible the gap between utmost point bar 1, the too much infiltration herein of anti-locking apparatus internal electric field. The upper aperture 21 of pole plate 2 is for Implantation or evict from. Wherein the pole plate 2 of one end is inlet electrode, and the pole plate 2 of the other end is exit electrodes.
Be further used as preferred embodiment, on described utmost point bar 1 and be provided with the sawtooth 12 of equidistant arrangement near the two ends of pole plate 2. Described sawtooth 12 is for fixing aperture plate 3.
Be further used as preferred embodiment, described through hole 11 be shaped as rectangle.
Be further used as preferred embodiment, the cross section of described utmost point bar 1 is circular arc.
Be further used as preferred embodiment, described utmost point bar 1 is stainless steel substrates.
Be further used as preferred embodiment, described aperture plate 3 adopts metal material to process.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
