Abstract
The utility model discloses a kind of single light source double suction receives pond gas phase molecular absorption spectrometer, there is light source, along the direction of light path circuit, be sequentially provided with the first absorption cell, the first speculum, the second speculum, the second absorption cell and detector.The utility model has the advantage that：Two absorption cells, can double sensitivity, substantially reduce test limit.
Description
Technical field
The utility model relates to optical instrument field, and in particular to a kind of single light source double suction receives pond gas-phase molecular absorption spectrometry
Instrument.
Background technology
Spectrometer is also known as spectrophotometer, is the scientific instrument that the light of complicated component is decomposed into spectrum line.Work as luminous intensity
For I0Light beam by concentration be C medium when, luminous intensity weakens to I, and it follows youth's primary-Bill absorption law：
A=lg (I0/ I)=KCL
A:Absorbance
I0:Incident characteristic spectral line radiates luminous intensity
I:It is emitted characteristic spectral line radiation luminous intensity
K:Absorption coefficient
L:Characteristic radiation light passes through flame distance
C:Concentration
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided a kind of double suction receives pond gas molecule in space is inhaled
Receive spectrometer.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of single light source double suction receives pond gas phase molecular absorption spectrometer, has light source, along the direction of light path circuit, successively
Provided with the first absorption cell, the first speculum, the second speculum, the second absorption cell and detector.
The utility model has the advantage that：
Sensitivity is doubled, substantially reduces test limit.
Brief description of the drawings
Fig. 1 is the structural representation of this practical single light source double suction receives pond gas phase molecular absorption spectrometer.
Embodiment
The utility model is further described with reference to embodiment, but the scope of protection of the utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1, a kind of single light source double suction receives pond gas phase molecular absorption spectrometer, there is light source 4, along light path line
Road 2-2 direction, it is sequentially provided with the first absorption cell 2, the first speculum 3, the second speculum 3-1, the second absorption cell 5 and detector
1。
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to above-mentioned each embodiment it is detailed
Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced
Change, and all do not depart from technical scheme and its improvement of spirit and scope of the present utility model, it all should cover new in this practicality
In the right of type.
