Description
Technical field
The utility model is related to a kind of spectral detection system, is applied especially with regard to one kind in analytical and testing instrument field
Light collecting circular dichroism detecting system.
Background technology
Circular dichroism (CD spectrum) is to determine one of effective ways of chipal compounds spatial configuration；Not only extensive use
In the identification of chipal compounds, the synthesis of chirality function material, device etc. and sign, it may also be used for chemical biology field, such as
Structure and the Characterization of The Interaction such as peptide, DNA, the stacking states of protein and its assembly.
Because sample size often selects micro quartz colorimetric utensil (slit 1-4mm), and rectangle light less in circular dichroism test
Spot width is about 5mm, and the effective area for causing sample surfaces to receive incident light is reduced, and luminous flux is reduced, so as to cause ultra-violet (UV) band
The spectrogram poor signal to noise of (such as near 200nm).
The content of the invention
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of light collecting circular dichroism detecting system, this is
System can meet lot of trace testing requirement, so as to effectively improve the CD spectral qualities of sample.
To achieve the above object, the utility model takes following technical scheme：A kind of light collecting circular dichroism detection system
System, it is characterised in that：The system includes base, sample holder, cuvette, slide rail, condenser, supporting plate and spectrum detection instrument；
The base is provided with and is provided with scale on slide rail, and the slide rail described in groove type；The sample holder is fixed on the cunning
Rail one end；The cuvette is placed on the sample holder, and the supporting plate lower slide is arranged in the slide rail, described
Condenser is placed in the supporting plate top, one end away from the condenser, is provided with corresponding with the cuvette position
The spectrum detection instrument.
Further, on the base, baffle plate is additionally provided with the extreme.
Further, the center of the condenser is centrally located in same horizontal line with the spectrum detection instrument.
Further, the spot size after the condenser is focused on to incident light is matched with the slit width of the cuvette.
Further, the cuvette uses micro quartz colorimetric utensil.
The utility model is due to taking above technical scheme, and it has advantages below：1st, the utility model is by condenser branch
Fagging is arranged in slide rail, is changed the distance between condenser and sample by mobile condenser, is realized launching spot size
It is adjustable, lot of trace testing requirement is met, the CD spectral qualities of sample are effectively improved.2nd, the utility model is in order to improve micro stone
English cuvette test in signal to noise ratio, incident light is focused using the adjustable condenser in position, make its spot size with it is micro-
The matching of quartz colorimetric utensil slit width is measured, and then ensures that all incident lights effectively pass through sample.3rd, the utility model chute type gathers
Light design improves to some extent to the spectral signal-noise ratio for improving instrument, lot of trace testing requirement can be met, so that preferably service department
Grind, it is significant.
In summary, the utility model can be applied in analytical and testing instrument field extensively.

On be provided with scale.Sample holder 2 is fixed on placement cuvette 4 on the one end of slide rail 3, sample holder 2；The lower slide of supporting plate 6
Be arranged in slide rail 3, condenser 5 is placed in the top of supporting plate 6, by the scale on slide rail 3 can accurately change condenser 5 with
The distance between cuvette 4, realizes to the adjustable of launching spot size, meets lot of trace testing requirement.Away from condenser 5
One end, is provided with spectrum detection instrument 7 corresponding with the position of cuvette 4.
In above-described embodiment, on base 1, baffle plate 8 is additionally provided with the end of slide rail 3, effectively to prevent supporting plate 6 from sliding
Go out slide rail 3.
In the various embodiments described above, center and the spectrum detection instrument 7 of condenser 5 are centrally located in same horizontal line.
In the various embodiments described above, the spot size after condenser is focused on to incident light is matched with the slit width of cuvette 4.
In the various embodiments described above, cuvette 4 uses micro quartz colorimetric utensil.
The utility model operating process is as follows：Sample is positioned in cuvette 4, passes through the condenser 5 that cuvette 4 is anterior
Incident light is focused, mobile condenser 5 causes its spot size to be matched with micro quartz colorimetric utensil slit width, it is ensured that institute
There is incident light effectively by sample.Changing the position of condenser 5 can realize to the adjustable of launching spot size, meet lot of trace
Testing requirement, so as to effectively improve the CD spectral qualities of sample, and then carries out effective detection by spectrum detection instrument 7 to sample.
The various embodiments described above are merely to illustrate the utility model, and structure and size, set location and the shape of each part are all
