Abstract
The utility model relates to a sample shelf for the sample-changing device of an X-ray diffractometer. The utility model is characterized in that the utility model is provided with a cycloid structure with a definite thickness made of magnetic material; the middle part of an outer wall is a peripheral concave groove, forming two peripheral outer edges; the edge of an inner diameter is provided with a sample groove. Compared with the imported sample shelf, the utility model has the advantages of lighter weight, smaller size, less material, and simpler process and manufacture. The utility model has no influence to the arrangement and taking out of the sample shelf and corrosion and deformation resistance. The utility model which reaches the analysis requirement can fully replace the imported sample shelf.
Description
The utility model relates to a kind of X-ray diffractometer sample changer specimen holder.
The automatic interchanger of five samples that uses on X-ray diffractometer such as the D/Max-1000 series diffractometer, improved the automaticity of instrument greatly, comprise five assembling dishes laying specimen holder on base, turntable, the turntable etc., with the contacted position of specimen holder four blocks of magnet are arranged on each assembling dish, the rotation of turntable and assembling dish is by motor driven.Specimen holder engages with the assembling dish, and the one, hang over by specimen holder on the axis of assembling dish, the one, coil last four blocks of magnet and specimen holder adhesive mutually by assembling, thereby the material of specimen holder to have ferromagnetism.
Diffractometer is an import equipment, and the import specimen holder is the aperture structure that the magnetisable material by the aluminium and the position that contacts with the assembling dish is composited, and there is sample cell at the internal diameter edge, and the outer helps arrangement and the taking-up of specimen holder on the assembling dish, and certain beauty function is arranged again.Such specimen holder light weight, firm, the difficult drop-off that combine with the assembling dish, the load of motor is little.Because many samples have corrosivity, the aluminium matter corrosion-resistant that contacts with sample, surface and groove that specimen holder uses the back to contact with sample can be corroded, corrosion thing meeting contaminated samples, influence needs the purity of keeping sample, even the impact analysis result, and such specimen holder needs to change.But import specimen holder price is rather stiff owing to be composite structure, is made trouble.
The specimen holder that the utility model provides substitutes the import specimen holder, and material is single, and is easy to make, and light weight can reach the analysis requirement fully.
X-ray diffractometer sample changer specimen holder of the present utility model is characterized in that it being to have a certain thickness ring structure with what magnetic material was made, is the border groove in the middle of the outer wall, forms two peripheral outers, and there is sample cell at the internal diameter edge.
The utility model selects for use single magnetic material to make, convenient processing and manufacture, as: the martensitic stain less steel class material with magnetic.Such material has more corrosion resistance and deformation resistance compared with aluminium.Thickness that most important two the size indexs of specimen holder are specimen holders and internal diameter (aperture of dress sample).The thickness of specimen holder will be with the consistent size of former import specimen holder, because the size of thickness influences the peak position that of diffraction peak.The too small meeting in the aperture of specimen holder is got on the specimen holder material outside the aperture ray, makes analysis result error message occur, so aperture otherwise less than the size of former import specimen holder.
Two outers of specimen holder, the forward position mainly is to be convenient to pick and place, with magnet on the assembling dish mutually an end outer of adhesive (back along) external diameter only otherwise influence use to inhale mutually and get final product with magnet.Because single magnetic material is heavier, can increase the load of CD-ROM drive motor, so in the middle of the external diameter border groove is set, weight reduction and unnecessary volume are suitable with former import specimen holder weight.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 4 sample cells of 1 internal diameter, 2 grooves, 3 outers
The whole sample frame is an integral structure, is made by magnetic material.Integral thickness 11mm, recess width 5mm, depth of groove 4.5mm, internal diameter (not carry sample groove) 24mm, maximum outside diameter 40mm is fit to five sample changers and uses.Its using method is with the import specimen holder, and aperture (internal diameter) structure of dress sample does not change.
Compare with the utility model and import specimen holder scanning samples:
Select the magnesium oxide standard specimen for use, diffraction peak with " 200 " crystal face of the utility model and import specimen holder scanning samples, the interplanar distance theoretical value of this crystal face is 2.106 dusts, interplanar distance is only got 2.11 dusts when reaching retrieval on the document, 2 θ theoretical values of peak position are 42.90 °, the peak position that scans with the import specimen holder is 42.896 °, interplanar distance 2.10657 dusts, the diffraction peak that scans with the utility model is 42.892 °, interplanar distance 2.10676 dusts, difference is minimum, can reach the analysis requirement fully, and the utility model can substitute the import specimen holder fully.
Advantage of the present utility model:
Quality is light, and is suitable with the import specimen holder, and volume is little, and materials are few, and processing and fabricating is simple, do not affect laying and getting of specimen holder Go out, have more corrosion resistance and deformation resistance, can reach the analysis requirement, fully can the replace imported specimen holder.
