Waste gas outlet is stated to communicate；
B, sampling：In the closed pad that first syringe needle is penetrated to enclosed sampling bottle, the second syringe needle is also inserted after continuing into
In the closed pad for entering enclosed sampling bottle, continue into, until the material inlet of the first syringe needle and the air admission hole of the second syringe needle are inserted
Enter to the inside of enclosed sampling bottle, during collection, liquid after the first syringe needle by being adsorbed into sampling bottle, and the second syringe needle can be inhaled
Getter body, after gas is by the second syringe needle, by sampling, syringe needle is discharged into active carbon adsorption device, completes sampling work.
Preferably, it is combined with the first cutting ferrule between first syringe needle and first mounting hole.
Preferably, it is combined with the second cutting ferrule between second syringe needle and second mounting hole.
The beneficial effects of the invention are as follows：Liquid sampling is carried out by using this method, gasket seal can be greatly reduced
Consumption, solve problem that syringe needle is blocked and the cost for reducing needle exchange head assembly, more importantly ensure that and normally take
Sample, it is ensured that safety in production.
