Abstract
A kind of ESEM is with exempting from conducting resinl sample holder, comprise sample holder pedestal, sample holder susceptor edges is surrounded with slideway, in slideway, be provided with the slide block that can slide along slideway, slide block end face is provided with Metallic rod, Metallic rod top is provided with conducting metal chain, and conducting metal chain one end is connected with Metallic rod top, and the conducting metal chain other end is provided with copper sheet and contacts with sample; The sample loading end of sample holder pedestal is provided with some conical supports, and conical support is evenly arranged in sample holder base bottom.That the design has is simple in structure, simple operation, the feature such as reduce costs, and the Metallic rod arranging on it and realized the conduction of sample holder and sample with the conducting metal chain that Metallic rod is used in conjunction with has been stopped a series of faults that cause because of use conducting resinl; Utilize conical support to support sample, can effectively avoid the vibrations that cause because of the trickle injustice of sample bottom, affect test data; The design, in effectively improving test scanning accuracy, has significantly reduced experimentation cost.
Description
Technical field
The utility model relates to the equipment in ESEM laboratory, refers to that particularly a kind of ESEM being used in conjunction with ESEM is with exempting from conducting resinl sample holder.
Background technology
In ESEM laboratory experiment, usually need sample inlay and the processing such as grind, then carry out observation analysis.Some sample conducts electricity, but it is good not to inlay resin conductivity, can affect the imaging effect of ESEM, therefore usually with conducting resinl, sample and sample stage is coupled together, to prevent charge accumulated on sample.Some nonmetallic materials, itself is just non-conductive, when analysis, except carbon, metal spraying will be sprayed in surface, yet with conducting resinl, spray carbon or metal spraying surface is coupled together with sample stage.But conducting resinl is running stores, with high costs, and discarded conducting resinl easily falls into the power transmission shaft of sample stage, also usually can cause mechanical breakdown.In addition, sample stage surface is plane, inlays the sample of sample or other type bottom almost plane, is directly put on sample stage, also usually can cause the small vibrations of bottom because of electronics bombardment, causes the unintelligible of picture, impact scanning accuracy.
Summary of the invention
The purpose of this utility model is exactly the defect that will overcome existing ESEM sample holder, provides one can improve sample electric conductivity, and then improves scanning accuracy, reduces the ESEM of experimentation cost with exempting from conducting resinl sample holder.
For achieving the above object, the designed ESEM of the utility model is with exempting from conducting resinl sample holder, comprise sample holder pedestal, its special character is: described sample holder susceptor edges is surrounded with slideway, in described slideway, be provided with the slide block that can slide along slideway, described slide block end face is provided with Metallic rod, and described Metallic rod top is provided with conducting metal chain, described conducting metal chain one end is connected with Metallic rod top, and the described conducting metal chain other end is provided with copper sheet and contacts with sample; The sample loading end of described sample holder pedestal is provided with some conical supports, and described conical support is evenly arranged in sample holder base bottom.
Further, described Metallic rod telescopic movable along its length.Like this, Metallic rod can, according to the actual height adjustment height of institute's scanned sample, be convenient to conducting metal chain and contact with sample.
Further, described conical support is provided with three, and its line is triangularly arranged at the sample loading end of sample holder pedestal.Like this, can improve sample and be placed on the stability on sample holder pedestal, prevent wobble effects scanning result.
The utility model has the advantage of: designed ESEM has simple in structure, simple operation, the feature such as reduces costs with exempting from conducting resinl sample holder, the Metallic rod arranging on it and realized the conduction of sample holder and sample with the conducting metal chain that Metallic rod is used in conjunction with, reduce test preparatory process, stopped a series of faults because using conducting resinl to cause; Utilize the conical support that sample holder base bottom arranges to support sample, the vibrations that cause because of the trickle injustice of sample bottom can effectively avoid by planar support time, affect test data; The design, in effectively improving test scanning accuracy, has significantly reduced experimentation cost, has good market prospects.
Brief description of the drawings
Fig. 1 is the structural representation of exempting from conducting resinl sample holder for the utility model ESEM.
In figure: slideway 1; Sample holder pedestal 2; Slide block 3; Metallic rod 4; Conducting metal chain 5; Copper sheet 6; Conical support 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
ESEM shown in figure is with exempting from conducting resinl sample holder, comprise sample holder pedestal 2, sample holder pedestal 2 edges are surrounded with slideway 1, in slideway 1, be provided with the slide block 3 that can slide along slideway 1, slide block 3 end faces are provided with Metallic rod 4, Metallic rod 4 telescopic movable along its length, and can do 360 ° of rotations around sample along slideway as required; Metallic rod 4 tops are provided with a conducting metal chain 5 that is about 20mm, and conducting metal chain 5 can be bending flexibly, and its one end is connected with Metallic rod 4 tops, and the other end is provided with copper sheet 6 and contacts with sample; The sample loading end of sample holder pedestal 2 is provided with three conical supports 7, the conical support 7 sample loading end that is evenly arranged in sample holder pedestal 2 triangular in shape.
This ESEM, with exempting from conducting resinl sample holder, uses step as follows:
1. sample is placed on to the conical support 7 on sample holder pedestal 2;
2. sliding metal bar 4 lower slider 3, make its arrival need position;
3. regulate the height of Metallic rod 4, make itself and specimen height roughly the same;
4. the copper sheet 6 of conducting metal chain 5 ends is positioned over to sample to be tested edge, makes sample and 2 conductings of sample holder pedestal;
5. sample is put into ESEM sample chamber, after vacuumizing, the operations such as laggard line scanning observation add high pressure.
