Description
Technical field
The utility model relates to the sample holder that a kind of spectrophotometric sample holder, particularly a kind of spectrophotometer read the logical light quantity/extinction amount of analysing solid sample, belongs to chemical analysis field.
Background technology
When spectrophotometer uses, is furnished with a sample holder.Sample holder plays fixed sample, makes light path accurately by sample, the effect of reading to realize the logical light quantity/extinction amount of spectrophotometer.
In the middle of the application of spectrophotometer great majority, sample holder is indispensable equipment.In existing spectrophotometer application, mostly be fluid sample concentration analysis, the sample holder of use is a liquid sample pool, and sample cell is put into and observed cabin, meanwhile, injects the fluid sample of q.s, can guarantee that light path passes through sample, completes reading of logical light quantity/extinction amount.
Yet in analytic process, spectrophotometer is also applied to the logical light quantity/extinction component analysis of solid sample often.Different from fluid sample, solid sample cannot pass through sample just by the cumulative light path that realizes of sample size, therefore need specific sample holder.Sample holder can be put sample on the one hand; Can realize on the other hand light path and just in time pass through sample.In addition, because in practical operation, solid sample size is various, shape is various, for a kind of sample size design sample support, can not meet the actual needs of several samples size, shape.
Utility model content
The purpose of this utility model is to provide a kind of spectrophotometer solid sample support simple in structure that reads analysis of logical light quantity/extinction amount of the solid sample applicable to various sizes, shape.
The utility model is achieved in that spectrophotometer solid sample support comprises a metallic object, on described metallic object, be provided with semicircle opening, groove, manhole, threaded hole, wherein said groove is that the square slotted eye and the described manhole that by multilayer sectional area, are varied in size form, and be a side that is machined in described metallic object, described manhole is arranged on the end of described groove, forming the center of square slotted eye and the center of described manhole that the multilayer sectional area of described groove varies in size is concentric structure, described threaded hole is arranged on the both sides of described groove and is symmetrical, two of the square slotted eye varying in size at the multilayer sectional area that forms described groove is processed with described semicircle opening on facing the wall and meditating.
The physical dimension of described metallic object and spectrophotometer sample cabin match.
Spectrophotometer solid sample support of the present utility model, owing to adopting said structure, can guarantee that light path, perpendicular to sample surfaces, is applicable to the analysis of the solid sample of sizes, various shapes, and simple in structure, easy to operate, analysis precision is accurate.

Fig. 2, Fig. 3, Fig. 4 are application implementation illustration of the present utility model.
Fig. 1 wherein---in Fig. 4: 1. semicircle opening 3. groove 4. manhole 5. threaded hole 6. samples of metallic object 2.
Embodiment
Below in conjunction with accompanying drawing, for embodiment, the utility model is described in further detail.
As shown in Figure 1, in the present embodiment, metallic object 1 is to adopt commercially available ingot to process, and its physical dimension is to match with the size in spectrophotometer sample cabin used, can put into cabin.Semicircle opening 2 is arranged on the symmetrical wall in two sides of each the square slotted eye that forms groove 3, only marks the semicircle opening 2 of one side in Fig. 1, be mainly used in sample taking-up, put into.Groove 3 is arranged on a side of metallic object 1, the square slotted eye being varied in size by multilayer sectional area and a manhole 4 form, by four descending structure one pyramidal structures of square slotted eye in the present embodiment, the foursquare center of four square slotted eyes and the center of manhole 4 are concentric structures, with light path center be also overlapping, such structure has guaranteed the logical photosensitiveness of specimen holder, manhole 4 the consistance that has guaranteed clear field is set, the square slotted eye of different cross section size is along the descending arrangement of light path incident direction, each limit of different square slotted eyes is parallel, being of uniform thickness of each limit.Manhole 4 is arranged on the end of groove 3.The quantity that has symmetrically threaded hole 5, every side threaded hole 5 in the two sides of groove 3 is identical with the quantity of square groove, is mainly the fixation playing sample.
Above-mentioned manhole 4 has guaranteed the consistance of various sample clear fields, and the square slotted eye sectional area size that the multilayer sectional area of formation groove 3 varies in size can be determined as required.Semicircle opening 2 is convenient to the installation replacing of sample.In the present embodiment, semicircle opening 2, groove 3, manhole 4, threaded hole 5 be machined making on metallic object 1 all, and groove 3 is on request in the cutting of side one deck slotted eye one deck slotted eye of metallic object 1.
Fig. 2-Fig. 4 is the schematic diagram of the various samples of the present embodiment.Absolutely proved versatility and applicability to different size, difformity sample, wherein dash area is sample 6, but is not limited only to the present embodiment.
With specimen holder by cross section 10mm * 10mm, 8mm * 8mm, 6.5mm * 6.5mm, tetra-layers of square slotted eye of 5mm * 5mm consist of example, and the application of different size, difformity sample is described.
Fig. 2 is the embodiment of square sample.One square sample sectional dimension is 4mm * 4mm.Be slightly less than cross section 5mm * 5mm square slotted eye.Square sample 6 is positioned over to cross section 5mm * 5mm slotted eye.By regulating the screw at threaded hole 5 places, sample is further fixed.Complete after sample reading, unscrew screw, with instruments such as tweezers, in semicircle opening 2 place's clamped sample, sample is taken out.For the square sample of other sizes, can select the square slotted eye of cross section suitable dimension.
Fig. 3 is the embodiment of circular sample.One circular sample 6 sectional dimensions are φ 5.Circular sample 6 is positioned over to cross section 5mm * 5mm square slotted eye.Complete after sample reading, with tool holding samples such as tweezers, sample is taken out.For the circular sample of other sizes, can select the square slotted eye of cross section suitable dimension.For some sample, can, by regulating the screw at threaded hole 5 places, sample further be fixed.
