The utility model has the advantages that: effectively improved the spatial resolution of energy spectrum, made the elemental composition's of qualitative analysis nanometer and submicron granule sample accuracy nature obtain improving, the device's overall stability is better, and what the fixed slot design of its side can be fine is fixed in the sample bench that is equipped with the screw with the device, and three preforming fixes the copper mesh on the top of carrying the net support, is favorable to under the high multiple condition that the appearance of sample granule is observed, the qualitative and distributional analysis of element of energy spectrum, and the device's suitability is better, and in the scanning electron microscope sample room that can put in any brand, the simple installation is swift.
Description
Technical field
The utility model relates to a kind of device for the accurate qualitative analysis nanoscale of ESEM power spectrum and submicron order material element composition.
Background technology
At present, the mode of ESEM fixed sample be mainly fixed in be stained with conducting resinl sample stage on carry out morphology observation and the analysis of power spectrum elemental composition, the weak point of this method is exactly the sample for nano-scale particle, conducting resinl below it and sample stage blocked up, electron beam through sample can not be penetrated, thus below sample, form larger interaction area, the spatial resolution of power spectrum reduces, the element information of matrix and neighboring particles can be caused all to display in target detection result, thus can not the elemental composition of accurate qualitative objective sample.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of ESEM copper mesh support.The technical solution of the utility model is: ESEM copper mesh support, comprises and carries net support and cantilever tip fixture, and this cantilever tip fixture removably connects with a year net support; Described net support entirety of carrying is arranged in convex shape, and comprise cylindrical base and screw rod integrated with cylindrical base, described screw rod is arranged on cylindrical base; Described screw rod and the inside of cylindrical base are the structure of hollow.
The overall cylindrical setting of described cantilever tip fixture, offer centre bore in the middle, the inwall of described centre bore is provided with the internal thread coordinated with external thread of screw; The cantilever tip fixture of described central hole is also provided with compressing tablet.
Described compressing tablet is three, and centrally the circumferencial direction in hole is evenly arranged.
The sidewall of described cylindrical base offers holddown groove.
Described year net support and cantilever tip fixture adopt aluminium alloy to be made.
The top of described screw rod is provided with step groove.
The utility model has the advantages that: the spatial resolution that effectively improve power spectrum, the accuracy that the element of qualitative analysis micro/nano level particulate samples is formed is improved; The resistance to overturning of this device is better, this device can well be fixed on and be equipped with on the sample stage of screw by the groove design of its side, copper mesh is fixed on the top of carrying net support by three compressing tablets, be conducive to the morphology observation of sample particle under high power said conditions, the qualitative elementary of power spectrum and distributional analysis, the applicability of this support is better, can be placed in the scanning electron microscope example room of any brand, simple installation is quick.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model.
Fig. 2 be carry in Fig. 1 net support and stent holder in conjunction with time structural representation.
Embodiment
Further describe the utility model below in conjunction with specific embodiment, advantage and disadvantage of the present utility model will be more clear along with description.But these embodiments are only exemplary, do not form any restriction to scope of the present utility model.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can modify to the details of technical solutions of the utility model and form or replace, but these amendments and replacement all fall in protection range of the present utility model.
See Fig. 1 and Fig. 2, the utility model relates to a kind of ESEM copper mesh support, comprises and carries net support 1 and cantilever tip fixture 2, and this cantilever tip fixture 2 removably connects with a year net support 1; In use, copper mesh 3 is arranged on the top of carrying net support 1, and described copper mesh 3 is fixed on and carries on net support 1 by this cantilever tip fixture 2.
Described net support entirety of carrying is arranged in convex shape, and height is 10mm, and comprise cylindrical base 11 and screw rod 12 integrated with cylindrical base 11, described screw rod 12 is arranged on cylindrical base 11; Described screw rod 12 and the inside of cylindrical base 11 are the structure of hollow.
Copper mesh 3 is arranged on the end of screw rod 12.The internal diameter of screw rod (because screw rod is hollow structure, so have internal diameter and external diameter) is 2.6mm,
The overall cylindrical setting of described cantilever tip fixture 2, outer diameter of a circle is 7mm, consistent with the outside diameter carrying net support 1, offer centre bore 21 in the middle, the diameter of centre bore 21 is 3.8mm, and described centre bore 21 inwall is provided with the internal thread coordinated with cored screw 12 external screw thread; The cantilever tip fixture 2 at described centre bore 21 place is also provided with compressing tablet 22, and described copper mesh 3 compresses by this compressing tablet 22, and thickness and the length of compressing tablet 22 are no more than 0.2mm.
In the present embodiment, described compressing tablet is three, and centrally the circumferencial direction in hole is evenly arranged.
The sidewall of described cylindrical base 11 offers holddown groove 13.
Described year net support 1 and cantilever tip fixture 2 adopt aluminium alloy to be made.
The top of described screw rod 12 is provided with step groove, and copper mesh is inserted in this step groove, and the degree of depth of step groove is 0.02mm,
Operation principle of the present utility model is: clamp the copper mesh edge covering and carry sample particle with tweezers, place it in the step groove of cored screw, be rotated down from carrying net frame upper direction threadingly with cantilever tip fixture, till three compressing tablets contact with copper mesh top edge, the assembling of this timer is complete; Can this device conducting resinl be adhered on sample stage, also can be fixed on and be equipped with in the sample stage of screw; After having tested, upwards back out cantilever tip fixture, take out copper mesh with accurate tip tweezers.
