Abstract
The utility model discloses a sample holder for an X-ray diffractometer and belongs to the technical field of X-ray diffraction analysis. The sample holder comprises adjusting screws (1), a sample holder body (2) and a top cover (4), wherein four screws are configured on the top cover (4), the top cover (4) is fixed on the sample holder body (2) through the screws, and the adjusting screws (1) are arranged on two sides of the sample holder body (2). During installation of a sample, the top cover is fixed on the sample holder body firstly to enable the surface of the to-be-tested sample to be closely attached to the top cover, then the to-be-tested sample is tightly fixed on the sample holder body through the adjusting screws on the two sides, the top cover is removed, and the sample holder body is fixed on a test bench. Thus, under the assistance of the top cover, the surface of the to-be-tested sample is overlapped with a focusing surface of X-rays, besides, the sample cannot move during testing due to fixation by the screws, and the measurement accuracy is guaranteed. The sample holder has the advantages that the sample holder is convenient to use, not affected by factors such as the size, the shape and the like of the sample and high in measurement accuracy; besides, multiple samples can be placed in the sample holder simultaneously, and quick switching of the samples is realized through movement of the left and right screws, so that the sample changing time is greatly shortened.
Description
Technical field
The utility model belongs to X-ray diffraction analysis technical field, particularly relates to a kind of specimen holder for X-ray diffractometer.
Background technology
X-ray diffraction technology has been widely used in crystal structure analysis, grating constant calculating, material phase analysis, textile analysis, macroscopical internal stress measuring etc., becomes the requisite measurement in many fields and the analysis means such as physics, chemistry, material science, geology and biology.
X-ray diffractometer is to carry out work according to the principle of Bragg diffraction, in the process of measuring, in order to ensure measuring accuracy, require the surface of sample strictly to overlap with the focussing plane of X ray, otherwise will cause the skew of diffraction peak, cause measuring error.In order to realize this point, in the time that powdered sample is measured, only powder need be poured into specific sample cell, flatten with glass sheet; And measure when bulk sample, due to the impact of different block size thickness differences, the unequal factor in bottom, often need to regulate by means of plasticine: first sample plasticine is adhered on test board, then press down gently sample with glass sheet, until the surface of sample coincides with the focussing plane of X ray.But, easily realize overlapping of tested surface and X ray focal plane although use plasticine, but when Measuring Time is long, plasticine is often subject to thermal softening to cause sample to move, cause sample surfaces in measuring process to depart from gradually the focussing plane of X ray, measure like this resultant error of coming very large.
Summary of the invention
The purpose of this utility model is to provide a kind of specimen holder for X-ray diffractometer.Solve the very large problem of error.
The utility model comprises: set screw 1, specimen holder main body 2, top cover 4; Wherein, on top cover 4, dispose 4 Screws, for top cover being fixed on to specimen holder main body 2.There is set screw 1 both sides of specimen holder main body 2.
In the time that sample is installed, first top cover is fixed on specimen holder, allow the surface label of sample press closer lid, then by the set screw of both sides, tested sample is tightly fixed on specimen holder, remove afterwards top cover, specimen holder is fixed on test board.Like this, under top cover auxiliary, sample surface overlaps with the focusing surface of X ray, and in addition, due to fixing of screw, in test process, sample can not move, thereby has guaranteed measuring accuracy.
This specimen holder is easy to use, is not subject to the impact of the factor such as sample size, shape; In addition, for the less sample of size, can be fixed on multiple samples on specimen holder simultaneously, after a sample has been surveyed, by moving left and right of 2 screws, directly on test board, realize the replacing of test sample like this, greatly shorten and vary the time.
Brief description of the drawings
Fig. 1 is the vertical view of X-ray diffractometer specimen holder.
Fig. 2 is the side view of X-ray diffractometer specimen holder.
Fig. 3 is the schematic diagram of top cover.
In figure, set screw 1, specimen holder main body 2, screw 3, top cover 4.
Embodiment
Further describe advantage of the present utility model and feature below in conjunction with accompanying drawing 1:
X-ray diffractometer specimen holder described in the utility model, comprises set screw 1, specimen holder main body 2, top cover 4, disposes 4 screws 3 on top cover, for top cover 4 is fixed on to specimen holder main body 2.
In the time that sample is installed, first top cover 4 use screws 3 are fixed in specimen holder main body 2, allow the surface label of sample press closer and cover 4, then by the set screw 1 of both sides, sample is tightly fixed in specimen holder main body 2, remove afterwards top cover 4, specimen holder main body 2 is fixed on the test board of X-ray diffractometer.Like this, under top cover 4 auxiliary, sample surface overlaps with the focusing surface of X ray, and in addition, due to fixing of set screw 1, in test process, sample can not move, thereby has guaranteed measuring accuracy.
In addition, for the less sample of size, can be fixed on multiple samples on specimen holder simultaneously, after a sample has been surveyed, by moving left and right of 2 set screw, directly on test board, realize the replacing of sample, thereby greatly shorten and vary the time like this.
