Abstract
The utility model discloses an elimination structure of bias light, include the base, locate pipeline on the base, the top of pipeline is equipped with the fender cover rather than the intercommunication, keep off the cover including bottom plate, riser, curb plate and apron and baffle, the bottom plate cup joints on the pipeline, the one end of bottom plate is provided with perpendicularly the riser, the other end of bottom plate is equipped with the curb plate, the curb plate with be equipped with 65 angles of inclination between the riser the apron, the bottom plate the riser the curb plate with it has the messenger to enclose between the apron it is sealed to keep off the cover the baffle, the inner wall of pipeline with fender cover inner wall all is equipped with inhales light -absorbing coating. The utility model discloses effectively reduce the instrument noise that light was turned back and is caused along former way.
Description
Technical field
This utility model belongs to evaporative light detector technologies field, and more particularly, to a kind of bias light eliminates structure.
Background technology
Evaporative light scattering detector is used for highly effective liquid phase chromatographic system, analyzes the chemical combination that any volatility is less than mobile phase
Thing.Evaporative light scattering detector can detect conventional detector non-detectable difficulty sample, is not subject to sample functional group or optics
The impact of property, can detect carbohydrate, medicine, lipid, triglyceride, not derivative fatty acid and aminoacid, polymer,
Surfactant and combination molecule storehouse etc..Its versatility of evaporative light scattering detector is better than ultraviolet absorption detector, sensitivity
Higher than refraction detector, evaporate photodetector and can obtain stable baseline in the case of multi-solvent gradient so that resolution is more preferable,
Separating rate is faster.The change of sample size in chromatography column effluent is converted to the signal being available for observing, is generally converted into
The signal of telecommunication, so that automatic record carries out qualitative and quantitative analysis.The detection light source of the detection means of existing evaporative light scattering detector
Light can part along backtracking, cause the noise of instrument to increase, lead to instrument detection performance reduction.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and provides a kind of elimination structure of bias light, from
And realize effectively reducing light and turn back the instrument noise causing along former road.In order to achieve the above object, this utility model technical side
Case is as follows:
The elimination structure of bias light, including base, the pipeline on described base；The top of described pipeline is provided with and it
The block cover of connection, described block cover includes base plate, riser, side plate and cover plate and baffle plate；Described base plate is socketed on described pipeline, institute
The one end stating base plate is vertically installed with described riser, and the other end of described base plate is provided with described side plate, and described side plate is vertical with described
It is provided with the described cover plate at 65 ° of inclinations angle, being between described base plate, described riser, described side plate and described cover plate makes between plate
The described baffle plate of described block cover sealing, the inwall of described pipeline and described block cover inwall are equipped with light-absorbing coating.
Specifically, the lower section of described base is provided with laser instrument.
Specifically, described pipeline is cylinder.
Specifically, described cover plate is provided with filter.
Compared with prior art, the having the advantages that of the elimination structure of this utility model bias light: using pipe
Light-absorbing coating in road and filter can effectively absorb laser instrument and inject the light in block cover；The cover plate at 65 ° of inclinations angle avoids
Because light is reflected back instrument noise that detection cell causes, improve instrument detection performance.
Brief description
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the front view of the present embodiment；
In figure numeral represents:
1 base, 2 pipelines, 3 block covers, 31 base plates, 32 risers, 33 cover plates, 34 side plates, 35 baffle plates, 4 depressed parts, 41 installations
Portion.
Specific embodiment
Clear, complete description will be carried out to the technical scheme in this utility model embodiment below in conjunction with the accompanying drawings it is clear that
Described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
Embodiment:
With reference to shown in Fig. 1-2, the present embodiment is the elimination structure of bias light, including base 1, the pipeline on base 1
2；Pipeline 2 is cylinder.The top of pipeline 2 is provided with the block cover 3 communicating therewith, and block cover 3 includes base plate 31, riser 32, cover plate 33, side
Plate 34 and baffle plate 35, base plate 31 is socketed on pipeline 2, and one end of base plate 31 is vertically installed with riser 32, the other end of base plate 31
It is provided with side plate 34, between side plate 34 and riser 32, be provided with the cover plate 33 at 65 ° of inclinations angle, cover plate 33, side plate 34, base plate 31 and riser
It is with the baffle plate 35 making block cover 3 seal between 32.It is provided with filter (in figure does not mark) in cover plate 33.The inwall of pipeline 2 and block cover 3
Inwall is equipped with light-absorbing coating (not shown).The lower section of base 1 is provided with laser instrument (not shown).The light of laser instrument
Enter in block cover 3 from the lower section of base 1.
For square and corner is provided with mounting hole site (in figure does not mark), the convenient laser instrument phase with light path entrance to base 1
Connect.Cover plate 33 is provided with depressed part 4, depressed part 4 be respectively provided on two sides with installation portion 41, installation portion 41 passes through bolt or nut
Molectron is fixedly connected on the hypotenuse of baffle plate 35.
Laser instrument can effectively be absorbed using the cover plate at 65 ° of inclinations angle in the present embodiment and inject light in block cover 3, keep away
Exempt to be reflected back, because of light, the instrument noise that detection cell causes, improved instrument detection performance.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality
New protection domain.
