The utility model solve the technical issues of be to overcome defect of the existing technology, a kind of multistage disassembly group is provided
Box-like the solvent analysis adsorption sampling pipe.The adsorption sampling pipe structure is simple, easy to use；The mode of dismountable can reduce suction
Attached dose scatters, and improves adsorbent elution efficiency；Every time in sampling, seal cap is dismantled, every time when elution, dismantling connection set
Pipe, convenient for improving economy.
To achieve the above object, the utility model provides the following technical solutions: a kind of multistage Assembled type the solvent analysis
Adsorption sampling pipe, including protection sleeve pipe, connecting sleeve and absorptive collection core, the absorptive collection core are at least two sections, and any
Two sections of absorptive collection core joints are socketed with connecting sleeve, and the connecting sleeve both ends are removably connected with protection sleeve pipe,
The sampling pipe both ends are respectively arranged with seal cap and air connections, and the absorptive collection in-core is filled with adsorbent.
Preferably, the whole both ends after the absorptive collection core connection are provided with the barrier of the silica wool for obstructing adsorbent
Layer.
Preferably, it is provided with air grid between the absorptive collection core adjacent both ends head, and the connecting sleeve is upper
O-ring seal is equipped in the two sides of air grid.
