Description
Technical field
The utility model is related to the technical field of organic amine substance sampling, more particularly, to a kind of amine sampling pipe.
Background technology
In the car, in track traffic and indoor and surrounding air, organic amine material is the allusion quotation for being only second to organic sulfur compound
Type odorant pollutant, has irritation, do harm to huamn body to eye, nose, throat.Sampling pipe common at present, absorbing liquid is only
For dimethylamine, trimethylamine, such as oxalic acid-glass microballoon sampling pipe, neutral silica gel pipe, its mesoxalic acid-glass microballoon sampling pipe has
Effect phase only one of which month, laboratory parsing, com-parison and analysis are cumbersome after sampling, are unfavorable for large batch of sample analysis, experimental result
Stability be difficult to ensure that；Absorbing liquid can solve sampling efficiency and parsing efficiency（It need not parse）, but absorbing liquid
Carry transport inconvenient.
In the prior art, the sampling of oxalic acid glass microballoon is fairly simple, but experiment post-processes cumbersome, batch processing difficulty after sampling
Greatly, the experiment degree of accuracy and poor reproducibility；Fibers adsorption pipe and silica gel absorption pipe absorption dimethylamine and trimethylamine utilize physical absorption,
It is with strong points；Absorb liquid energy and improve adsorption efficiency, but absorbing liquid is unfavorable for storing and transported.Auto parts and components, track traffic and
There are fatty amines, aromatic amine, other amines etc. to be not limited to dimethylamine and trimethylamine in surrounding air.
The content of the invention
The utility model is to overcome at least one defect described in above-mentioned prior art there is provided a kind of amine sampling pipe, can be adopted
Collect more volatile organic amines, improve sampling efficiency and analyzing efficiency, subsequent treatment is simple and easy to carry.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of amine sampling pipe, wherein, including
The both ends of glass tube are provided with closure after filling glass cotton, sampling in glass tube, glass tube.
In the utility model, including：Blank pipe, pretreated mineral wool, closure；Blank pipe makes for glass, and mineral wool is
Pretreated through phosphoric acid, sampling pipe is that the pretreated mineral wool of certain mass is filled in glass tube, high-temperature digestion two ends
Glass capsulation is preserved, the sampling pipe being made.
Further, described glass tube includes glass tube main body, the glass tube leading section located at glass tube main body one end.
Described glass tube main body is shaped as cylindrical shape.Being shaped as described glass tube leading section is coniform.Glass tube main body master
Play a part of carrying, the inside is equipped with pretreated mineral wool.The diameter of glass tube leading section is gradually reduced, glass tube front end
The shape in portion is similar to be coniform.
Further, described glass tube main body and the junction of glass tube leading section are provided with screens, described mineral wool
One end be connected in screens.In the utility model, screens is a raised structure, can block mineral wool, prevents it in sampling
In-pipe.In addition, in order to block mineral wool, may be alternatively provided as other interface arrangments, above-mentioned interface arrangment is in this reality
With in new protection domain.
Further, the end of described glass tube main body is provided with the first cutting mouth, and described glass tube front end is set
There is the second cutting mouth.During sampling, opened at the first cutting mouth, the second cutting mouth, gas flow direction is the second cutting mouth end
Enter, the first cutting mouth is brought out, complete after sampling, preserved after sampling pipe two end cap top cover labyrinth.
Compared with prior art, beneficial effect is：This sampling pipe of the utility model can gather more volatile organic amines, carry
High sampling efficiency, analyzing efficiency, subsequent treatment is simple and easy to carry.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
