Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
the gas sampling device comprises a sampler 1, a gas detector 2, a gas sampling hose 3, a liquid preparation tank 4, a gas overflow outlet 5, a clamp 6, a clamp 7, a gas sampling hose 8 and a sampling needle.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in figure 1, a novel self-made gas sampling device comprises a sampler 1 for collecting and storing gas and a gas detector 2 for detecting gas content, wherein the sampler 1 is a plastic injector, and the specification of the plastic injector is 100cc or 200 cc. The port of the sampler 1 is connected with the air outlet port of the gas sampling hose 3, the air inlet port of the gas sampling hose 3 is connected with the gas overflow port 5 of the liquid preparation tank 4, the front end of the air inlet end of the gas sampling hose 3 is provided with a clamp 6 for closing and isolating the gas sampling hose 3 after gas collection, and the clamp 6 is hemostatic forceps. The gas detector 2 is connected with a sampling needle 8 through a gas sampling hose 7, the sampling needle 8 is inserted into the gas sampling hose 3 close to the port of the sampler 1 in an inclined manner, and the inclined angle is preferably 30-45 degrees.
The specific embodiment is as follows: the sampler 1 adopts a 200cc plastic injector, the gas detector 2 adopts a headspace residual oxygen instrument, the gas in the liquid preparation tank 4 is nitrogen, and the clamp 6 adopts hemostatic forceps.
The air inlet port of the gas sampling hose 3 is inserted into the gas overflow port 5 of the liquid preparation tank 4, the piston rod of the syringe is slowly sucked up and down by hand for 3-5 times to displace the residual air in the plastic syringe and the gas sampling hose 3, then 200ml of nitrogen is extracted by the plastic syringe, the front end of the air inlet end of the sampling hose is tightly clamped by a hemostatic clamp, and at the moment, the protective nitrogen filled in the liquid preparation tank is collected into the 200cc plastic syringe.
The gas sampling hose 3 with the collected nitrogen sample is removed from the gas overflow port 5, and the sampling needle 8 on the headspace oxygen residue meter is inserted into the gas sampling hose 3 close to the port of the sampler 1 in an inclined way, wherein the inclined angle is preferably 30-45 degrees. Press "detection key" on the headspace oxygen residual instrument panel, nitrogen gas residual oxygen numerical value in the instrument meeting automated inspection and the demonstration plastic syringe, the utility model discloses a irritate 4 and gas sampling hose 3 interior nitrogen gas residual oxygen value's quick sample and detection to joining in marriage the liquid under the off-line mode.
