Abstract
The utility model discloses a double-thermal-conductivity detector, wherein an analysis pool and a reference pool are disposed in a pool body; an analysis gas inlet and an analysis gas outlet communicated with the analysis pool as well as a reference gas inlet and a reference gas outlet communicated with the reference pool are connected to the pool body; a spare analysis pool is further disposed in the pool body; and a spare analysis gas inlet and a spare analysis gas outlet communicated with the spare analysis pool are further connected to the pool body. The double-thermal-conductivity detector disclosed by the utility model has the advantage of being long in service life.
Description
Technical field
The utility model belongs to the detecting instrument technical field, relates in particular to a kind of pair of thermal conductivity detector (TCD).
Background technology
Thermal conductivity detector (TCD) (TCD) claims that again conductance cell or heated filament examine hot device, is the most frequently used a kind of detecting device of vapor-phase chromatography, is based on that different component has the principle of different thermal conductivities with carrier gas and the thermal conductivity detector of working.The Chi Tizhong of existing thermal conductivity detector (TCD) has only a group analysis pond and one group of reference cell, instead gives birth to damage in case the defective that such thermal conductivity detector (TCD) exists is this only group analysis pond, and whole thermal conductivity detector (TCD) just can not use.
The utility model content
For this reason, the utility model provides a kind of pair of thermal conductivity detector (TCD), overcomes only group analysis pond damage in the prior art and the out of use defective of whole thermal conductivity detector (TCD).
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pair of thermal conductivity detector (TCD); In the body of pond, have analysis cell and reference cell; Be connected with the import of branch gassing, the outlet of branch gassing that are communicated with analysis cell on the body of said pond; The reference gas import that is communicated with reference cell, reference gas outlet is characterized in that: also have subsequent use analysis cell in the body of said pond, also be connected with the gassing import in subsequent use minute and the gassing outlet in subsequent use minute that are communicated with subsequent use analysis cell on the body of said pond.
In the embodiment of the utility model, said reference cell is positioned in the middle of analysis cell and the subsequent use analysis cell.And, said analysis cell, reference cell and subsequent use analysis cell be that two parallel connections are communicated with cell cavity.
Owing at Chi Tizhong two analysis cells are arranged,, can also utilize the another one analysis cell to continue to cooperate detection, thereby need whole thermal conductivity detector (TCD) not scrapped with reference cell even an analysis cell has damaged like this.Therefore, the utlity model has the advantage of long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the structural representation of the utility model;
Among the figure:
100-pond body, 200-analysis cell, 201-divide the gassing import, and 202-divides the gassing outlet, 300-reference cell, the import of 301-reference gas, the outlet of 302-reference gas, the subsequent use analysis cell of 400-, 401-gassing import in subsequent use minute, 402-gassing outlet in subsequent use minute.
Embodiment
As shown in Figure 1, two thermal conductivity detector (TCD)s of the utility model have analysis cell 200, reference cell 300 and reference analysis pond 400 in pond body 100.Analysis cell 200, reference cell 300 and subsequent use analysis cell 400 be that two parallel connections are communicated with cell cavity.Wherein, reference cell 300 is positioned in the middle of analysis cell 200 and the subsequent use analysis cell 400.Export 201 and on pond body 100, be connected with the branch gassing import 201, the branch gassing that are communicated with analysis cell 200; The reference gas import 301 that is communicated with reference cell 300, reference gas outlet 302, gassing import in subsequent use minute 401 that is communicated with subsequent use analysis cell 400 and gassing outlet 402 in subsequent use minute.
Owing at Chi Tizhong two analysis cells are arranged,, can also utilize the another one analysis cell to continue to cooperate detection, thereby need whole thermal conductivity detector (TCD) not scrapped with reference cell even an analysis cell has damaged like this.Therefore, the utlity model has the advantage of long service life.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (3)
1. two thermal conductivity detector (TCD); In the body of pond, have analysis cell and reference cell; Be connected with the import of branch gassing, the outlet of branch gassing that are communicated with analysis cell on the body of said pond; The reference gas import that is communicated with reference cell, reference gas outlet is characterized in that: also have subsequent use analysis cell in the body of said pond, also be connected with the gassing import in subsequent use minute and the gassing outlet in subsequent use minute that are communicated with subsequent use analysis cell on the body of said pond.
2. pair thermal conductivity detector (TCD) according to claim 1 is characterized in that: said reference cell is positioned in the middle of analysis cell and the subsequent use analysis cell.
