Description

A kind of Micro-CT scanning efficiently scans sample stage
Technical field
The present invention relates to a kind of sample stages, and in particular to a kind of Micro-CT scanning efficiently scans sample stage.
Background technology
Micro-CT scanning(Micro-Computed Tomography), it is also referred to as X-ray microfault photography.Refer to space point Resolution can reach the CT of lum or so.The main composition of Micro-CT scanning includes X radiographic sources, specimen rotating holder and detector three Part.X-ray source and detector are fixed, and sample rotates between X radiographic sources and detector, and cone is continuously generated by X radiographic sources The X beams of shape penetrate sample to be tested, are imaged on X-ray detector, and rate rotates sample at an angle, Obtain x-ray perspective view of the sample in different angle.By corresponding computer software, by the projected image of each angle into Row reconstruct, is reduced into the analyzable 3D rendering in computer.Specimen rotating holder is made of rotating base and sample stage, sample One end insertion rotating base center of platform, and fixation can be attached thereto, the other end of sample stage holds sample.Sample stage at present It is simple in structure to hold the place of sample, is typically plane or concave surface(Such as patent 201410513981.X, a kind of synchrotron radiation X is penetrated Line Micro CT imaging sample stage), it is more convenient for common block sample operation, but for powder, cotton-shaped or liquid sample, behaviour Make to get up just relatively difficult or can not use, if it is desired to improving efficiency, run-down completes the test of several samples, just more It is difficult to operate.
The content of the invention
It is an object of the invention to overcome the shortage of prior art, one kind is provided and is carried out for powder, cotton-shaped or liquid sample The sample stage that Micro-CT scanning efficiently scans.
Detailed description of the invention
The present invention provides a kind of carries out the sample stage that Micro-CT scanning efficiently scans, the sample stage for powder, cotton-shaped or liquid sample Including:Supporting rod, sample cell and obturator, supporting rod are vertical with sample trench bottom.
Described supporting rod one end is connected with instrument rotating base, and one end is connected with sample cell, is connected with instrument rotating base Partly its shape specification will reserve attachment device with pedestal and match, highly according to instrument it needs to be determined that, with sample cell coupling part For cylinder, screw thread is arranged at top, mating with the threaded hole of sample trench bottom, and material is metal.
For the sample cell to have round-ended cylinder, outer diameter 5-30mm, material is light plastic.It is divided into as needed multiple only Vertical space, wherein, the space bottom of center is circle, and with sample trench bottom concentric, partition space is vertical with partition In sample trench bottom;Sample cell base thickness 1-2mm ensures firm and durable, and centre bit is equipped with below sample trench bottom and supporting rod connects The thickening threaded hole component connect;Barrel and segmentation partition are as far as possible thin on the premise of guaranteeing to hold sample, and sample cell is high 5-10mm。
The obturator is light plastic foam, has the light materials such as certain sticky solid paraffin, is needing fixed sample It is used when grade is put.
Advantageous effect
The sample stage of the present invention solves the problems, such as the rapid prototyping of the samples such as powder, cotton-shaped, liquid, can also hold simultaneously multiple Different samples, greatly improves testing efficiency.For measuring few sample, first central part space can be will be far from obturator and filled out Come, sample is allowed to concentrate on close to central part, its test result is made to become apparent from accurately.Sample cell center space is cylinder Body, in test, it is only necessary to pay close attention to the sample segment, adjust between two parties.Barrel used, partition are light material, It is less to X-ray absorption, test image quality is not influenced.
Description of the drawings
Fig. 1 is that the Micro-CT scanning of the embodiment of the present invention efficiently scans sample stage structure diagram;
Fig. 2 is the sample cell top view of the embodiment of the present invention;
Fig. 3 be the embodiment of the present invention sample cell in obturator position view(It overlooks).
Specific embodiment
With reference to embodiment and Figure of description, the present invention is further elaborated, but institute's protection domain of the present invention is not limited to This.
The embodiment of the present invention provides one kind and carries out Micro-CT scanning for powder, cotton-shaped or liquid sample(Bruker SkyScan 2211 types)Five sample stages efficiently scanned, in test scanning of the resolution ratio more than 1 micron.The sample stage includes:Support Bar, sample cell and obturator, supporting rod are vertical with sample trench bottom.
The supporting rod is cylinder(Because 2211 type instrument rotating bases of Bruker SkyScan reserve connecting hole as circle Shape), diameter 6.5mm, material is copper.One end is connected with 2211 Micro-CT scanning rotating bases of Bruker SkyScan, the other end and sample Product slot connects, and screw thread is arranged at top, mating with the threaded hole of sample trench bottom.
The sample cell is has round-ended cylinder, and outer diameter 10mm is highly 8mm, and material is polypropylene plastics.Segmentation as needed Into five separate spaces, wherein, the space bottom of center is circle, internal diameter 3mm, and with sample trench bottom concentric, point Space partition is cut perpendicular to sample trench bottom.Sample cell base thickness 1.5mm, centre bit is equipped with and supporting rod below sample trench bottom The thickening threaded hole component of connection.Barrel and segmentation partition are as far as possible thin on the premise of guaranteeing to hold sample, and thickness is 0.2mm。
The obturator is the light materials such as light plastic foam and correction wax, when needing fixed sample position with making, Such as measuring few sample, first appropriately sized plastic foam can be sticked on the position away from central part with correction wax, is filled out A part of space allows sample to concentrate on close to central part, is unlikely to thinly to be dispersed in bottom, makes test effect more It is good.
Above example is merely to illustrate the present invention and is used rather than limitation of the present invention, the technology people in relation to technical field Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent Technical solution should also belong to scope of the invention, should be limited by each claim.
