When the sampling bag is used, gas in the sampling bag is pumped out in a manual mode or an air pump, the rubber tube is sealed, the sampling bag is placed into a pressure bearing bottle, the bottle cap is screwed, the air pump is connected to the air pump, the stop valve is opened, the air pump is started, air pressure in the pressure bearing bottle is pumped to negative pressure, and the stop valve is closed; when sampling is carried out on site, the rubber tube is opened, gas is rapidly filled into the sampling bag, the change condition of the sampling bag is observed through the pressure bearing bottle, and when the sampling bag is full, the stop valve is rapidly opened to enable the air pressure inside and outside the sampling bag to be balanced; closing the stop valve and sealing the rubber tube; and (4) transporting the collected sample back to the laboratory in a dark place, opening the stop valve after an analyst receives the sample, and extracting the sample with the corresponding volume from the rubber tube by using the syringe for analysis.
The utility model has the advantages that:
1. the device is light, portable and not easy to break, and reduces the burden of field sampling personnel;
2. the pressure-bearing bottle is a transparent bottle, so that the change condition of a sampling bag in the bottle can be observed in real time, and the condition of insufficient gas production or excessive gas production can be effectively avoided;
3. the odor sample is directly collected by the sampling bag, so that the adsorption of the glass material to certain components in the odor sample can be effectively avoided;
4. the collection process of the sample is realized through atmospheric pressure difference, an air suction pump is not required to be arranged during field sampling, and the application range is wide;
5. when the collected odor sample is analyzed in a laboratory, a polyester lining bag is not required to be added to maintain pressure balance, so that the disturbance to the sample is avoided;
6. laboratory analysts directly extract the foul smell sample from the rubber tube for analysis, and the pressure inside and outside the sampling bag is always kept balanced after the stop valve is opened, so that the air extraction difficulty of the analysts can be effectively reduced, and the analysis efficiency is improved.
