Abstract
The utility model refers to the technical field of spectral analysis instrument, particularly refers to a sheath-type sample holder, wherein the sheath-type sample holder provided in the utility model is adding a sheath over an outer wall of a sample pool; four sides of the sheath are provided with a light inlet window. The sheath-type sample holder provided in the utility model allows the sample pool with various ultraviolet or fluorimetric determination, and in the repeated operation process, cleanliness and light transmittance of the instrument are guarantied. The utility model has simple structure, low cost, easy operation, and is easy to be promoted.
Description
Technical field
The utility model relates to the spectrometric instrument technical field, is specifically related to a kind of protective-cover type specimen holder.
Background technology
When adopting spectrometric instrument that fluid sample is measured, because the tester must insert sample cell or extract out in the instrument specimen holder continually with hand, carry out fluid injection, mensuration, fall liquid, cleaning, fluid injection again, mensuration ... Deng repetitive operation.In case misoperation can make the outer wall transparent surface of sample cell be subjected to for example contamination such as impression of the hand or waste liquid, influences measurement result, especially when doing the on-site sampling analysis such as places such as petroleum drilling, field tests, the risk of being operated contamination can be bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of protective-cover type specimen holder, the outer wall that also is to sample cell installs a sheath additional, make sample cell in operating process repeatedly, keep the cleanliness and the light transmission of its outer wall, with accuracy and the repeatability of guaranteeing instrument test.
A kind of protective-cover type specimen holder that the utility model provides is that the outer wall at sample cell installs a sheath additional, there is light inlet window at the four sides of sheath, the protective-cover type specimen holder of Xing Chenging can make sample cell carry out various ultraviolets or fluorometric assay like this, and in operating process repeatedly, the cleanliness and the light transmission that keep its outer wall are guaranteed the accuracy and the repeatability of instrument test.
The utility model both can be used as the anti-sample cell sheath that stains, and was again a kind of traditional specimen holder.Both, be more suitable in the fluorometric assay of four sides printing opacity sample cell applicable to the ultraviolet determination of two printing opacity sample cells.The utility model is simple in structure, with low cost, easy to use, be easy to promote.
Below, describe details and working condition in conjunction with the accompanying drawings and embodiments in detail according to the concrete device that the utility model proposes.
Description of drawings
The protective-cover type specimen holder structural representation that Fig. 1 provides for the utility model embodiment.
Embodiment
A kind of protective-cover type specimen holder that the utility model provides is that the outer wall at sample cell installs a sheath additional, there is light inlet window at the four sides of sheath, the protective-cover type specimen holder of Xing Chenging can make sample cell carry out various ultraviolets or fluorometric assay like this, and in operating process repeatedly, the cleanliness and the light transmission that keep its outer wall are guaranteed the accuracy and the repeatability of instrument test.
As shown in Figure 1, a kind of protective-cover type specimen holder of providing of the utility model embodiment is made up of sheath frame 1 and filler rod 2.Described sheath frame 1 is the hexahedron of a tool four columns, and its three sides respectively are provided with a light inlet window 1a, and the front is the doorframe 1b that packs into of sample cell 3.The physical dimension of the hexahedron inner cavity size of sheath frame 1 and sample cell 3 hexahedrons is complementary, but dressing whole sample pond.Sample cell 3 by doorframe 1b pack into use up and down filler rod 2 press seals again after, can not move again.Like this, it is more suitable in the fluorometric assay of four sides printing opacity sample cell both applicable to the ultraviolet determination of two printing opacity sample cells.
There is a square horn interface 1c who is slightly less than the sample cell opening on the top of described sheath frame 1, not only can block the upper edge of sample cell but also be convenient to the injection of sample liquid, pours out or cleans.
In addition, the base 1d size of described sheath frame 1 must be complementary with the size of packing into of instrument specimen holder.So, the tester need not directly contact the outer wall of sample cell, can carry out normal running.
The utility model manufacturing materials, method are not limit, and can adopt metal material processing, screw splicing or other forming methods.For example the utility model can also be designed to the no Door frame frame of a four sides printing opacity, and sample cell inserts from the top, adds a frame lid and fixes, and the filler rod that is different from front embodiment is fixed.In addition, the utility model generally can adopt etch-proof nonmetallic materials machine-shaping, has more the performance of anticorrosion, anti-use.
In sum, more than the detailed description of preferred specific embodiment, be to wish know more description technical characterictic of the present utility model, and be not to come category of the present utility model is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain in the scope that is arranged in the utility model protection of various changes and tool equality.
Claims (3)
1, a kind of protective-cover type specimen holder is characterized in that this protective-cover type specimen holder is that outer wall at sample cell installs a sheath additional, and there is light inlet window at the four sides of sheath.
2, a kind of protective-cover type specimen holder according to claim 1 is characterized in that the protective-cover type specimen holder is made up of sheath frame (1) and filler rod (2); Described sheath frame (1) is the hexahedron of a tool four columns, and its three sides respectively are provided with a light inlet window (1a), and the front is the doorframe of packing into (1b) of sample cell (3); The physical dimension of the hexahedron inner cavity size of sheath frame (1) and sample cell (3) hexahedron is complementary, but dressing whole sample pond; Sample cell (3) by doorframe (1b) pack into use up and down filler rod (2) press seal again after, can not move again.
3, a kind of protective-cover type specimen holder according to claim 2, the top that it is characterized in that described sheath frame (1) have a square horn interface (1c) that is slightly less than the sample cell opening.
