Abstract
The invention 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 device have the advantages that：Two absorption cells, can double sensitivity, substantially reduce test limit.
Description
Technical field
The present invention relates to optical instrument field, and in particular to a kind of single light source double suction receives pond gas phase molecular absorption spectrometer.
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
The content of the invention
The invention aims to make up the deficiencies in the prior art, there is provided a kind of double suction receives pond gas molecule in space absorbs light
Spectrometer.
In order to reach the purpose of the present invention, 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 device have the advantages 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
With reference to embodiment, the invention will be further described, but protection scope of the present invention is not limited solely to implement
Example.
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 technology described in the invention to illustrate the present invention
Scheme, therefore, although this specification with reference to above-mentioned each embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution, and all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
