Description
Technical field
The present invention relates to a kind of spectrophotometric sample holder, particularly a kind of spectrophotometer reads the sample holder that analysing solid sample leads to light quantity/extinction amount, belongs to chemical analysis field.
Background technology
When spectrophotometric uses, be all equipped with a sample holder.Sample holder plays fixed sample, makes light path accurately by sample, to realize the reading that spectrophotometer leads to light quantity/extinction amount.Because spectrophotometric spot size is little, therefore the support of sample is absolutely necessary when using spectrophotometer, and current spectrophotometric application is mostly fluid sample concentration analysis, the sample holder used is a liquid sample pool, sample cell puts into spectrophotometric observation cabin, meanwhile, inject the fluid sample of q.s, can ensure that light path passes through sample, complete the reading analysis of logical light quantity/extinction amount.Along with the development of S&T tax, spectrophotometer is not only confined to fluid sample analysis, also will to the logical light quantity/extinction quantitative analysis of various solid sample, different from fluid sample, solid sample does not pass through sample just by the cumulative light path that realizes of sample size, therefore regarding businesses have developed various solid sample support, if China Patent No. is 20072007149.7(specimen holder), 201020293270.3(spectrophotometric solid sample holder) etc., though these specimen holders can make light path just by sample, structure is also simpler, but various shape can not be applicable to, the sample analysis that size differs, precision is not good enough yet.
Summary of the invention
The object of this invention is to provide one and can be applicable to various shape, the different solid sample of size lead to light quantity/extinction amount read analyze, the simple spectrophotometer sample holder of structure.
The present invention is achieved in that it comprises a metallic object, described metallic object is provided with semicircle opening, groove, manhole, threaded hole, wherein said groove is that the square slotted eye that varied in size by multilayer sectional area and described manhole are formed, and be the side being machined in described metallic object, described manhole is the end being arranged on described groove, the center of the square slotted eye that the multilayer sectional area forming described groove varies in size and the center of described manhole are concentric structures, described threaded hole be arranged on described groove both sides and be symmetrical, described semicircle opening is processed with on facing the wall and meditating form the square slotted eye that the multilayer sectional area of described groove varies in size two.
Physical dimension and the spectrophotometer sample cabin of metallic object match.
Solid sample bracket of spectrophotometer of the present invention, owing to adopting said structure, therefore can ensure that light path is perpendicular to sample surfaces, is applicable to sizes, the solid sample analysis of various shape, structure is simple, easy to operate, analysis precision is accurate.

Fig. 2, Fig. 3, Fig. 4 are Application Example of the present invention.
Wherein Fig. 1---in Fig. 4: 1. metallic object 2. semicircle opening 3. groove 4. manhole 5. threaded hole 6. sample
Embodiment
Below in conjunction with accompanying drawing, for embodiment, the invention will be further described.
As shown in Figure 1, in the present embodiment, metallic object 1 adopts commercially available ingot to process, and its physical dimension matches, namely putting into cabin with the size in spectrophotometer sample cabin used.Size as spectrophotometric cabin is 14 × 12 × 12mm, then the size of metallic object should be 12 × 10 × 10mm.First machined in a side of metallic object 1, as being cut into groove 3 with cutting mode one deck slotted eye one deck slotted eye.Have four layers of slotted eye in the present embodiment and cross section is all foursquare, be respectively 10mm × 10mm, 8mm × 8mm, 6.5mm × 6.5mm, 5mm × 5mm, the thickness on each limit of each square slotted eye is the same, and each limit is parallel.So just form the groove 3 of a turriform shape.Manhole 4 is out the end at groove 3, the i.e. end of an in the end square slotted eye, the end at 5mm × 5mm square slotted eye in the present embodiment, the center of the circular central of manhole 4 and four square slotted eyes of groove 3 is concentric structures, also be overlapping with the center of light path, such structure ensure that the logical photosensitiveness of sample holder, the consistance of clear field, the square slotted eye of different cross-sectional size is applicable to place different size, difform sample, and the square slotted eye of different cross-sectional is along the descending arrangement of light path incident direction.Semicircle opening 2 is arranged on two Symmetry Edges of each square slotted eye forming groove 3, only marks the semicircle opening 2 on a limit in FIG, is mainly used in the taking-up of sample, puts into.Threaded hole 5 be opened in groove 3 two sides and be symmetrical on a surface level, the quantity in each flank threads hole 5 is the same with the quantity (being 4 in the present embodiment) of the square slotted eye of groove 3, is mainly used in fixing sample.
Above-mentioned manhole 4 ensure that the consistance of various sample clear field, and its size of square slotted eye that the multilayer sectional area forming groove 3 varies in size can be determined as required.The installation that semicircle opening 2 is convenient to sample is changed.In the present embodiment, semicircle opening 2, groove 3, manhole 4, threaded hole 5 are all machined on metallic object 1 to be made, 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 various sample in the present embodiment.For sample holder cross section be 10mm × 10mm, the groove 3 that formed of 8mm × 8mm, 6.5mm × 6.5mm, 5mm × 5mm tetra-layers of square slotted eye illustrates the application of different size, difformity sample.
Fig. 2 is the embodiment of square sample 6, one sectional dimension is the square sample 6 of 4mm × 4mm, sample 6 is placed on by semicircle opening 2 in the square slotted eye of groove 3 middle section 5mm × 5mm, by regulating the screw of threaded hole 5, sample 6 is fixed, then whole sample holder is put into spectrophotometer sample chamber used indoor to analyze sample 6, after completing required reading, unclamp the screw at threaded hole 5 place, take out from semicircle opening 2 again, for the square sample of other size, as long as select the square slotted eye of suitable cross-section size.
Fig. 3 is sample 6 is circular, sectional dimension is φ 5, sample 6 is placed on by semicircle opening 2 in the square slotted eye of the cross section 5mm × 5mm in groove 3, by regulating the screw of threaded hole 5, sample 6 is fixed, then whole sample holder put into spectrophotometer sample chamber used indoor sample 6 is analyzed, unclamp the screw at threaded hole 5 place after completing required reading, then take out from semicircle opening 2.As long as select the square slotted eye of suitable cross-section size to the circular sample of other size.
Fig. 4 is sample 6 is rectangles, and sectional dimension is 7mm × 4mm, as long as put it in the cross section 8mm × 8mm square slotted eye in groove 3, can complete required reading, then take out from semicircle opening 2 by above-mentioned same method of operating.Rectangle sample for other sizes can select the square slotted eye of suitable cross-section size.
The versatility to different size, difformity sample and applicability can be absolutely proved from above-described embodiment, but be not limited only to above-mentioned several embodiment.
Because solid sample bracket of spectrophotometer of the present invention have employed above-mentioned structure, therefore can ensure that light path is by sample to be analyzed, its light path, perpendicular to sample surfaces, ensure that the consistance of logical photosensitiveness, clear field, and sample holder structure is simple, integrated level is high, analysis precision is high.
