2. Technical scheme
In order to achieve the purpose, the technical scheme of the invention is as follows: a portable sampling bag for a gas chromatograph comprises an air bag body and a rubber sleeve; one end of the air bag body is provided with an opening along the axial direction, and the opening extends along the axial direction of the air bag body to form an air inlet cylinder; the air inlet cylinder and the air bag body are of an integral structure; a steel groove is fixedly arranged on the inner side of the air inlet cylinder, and a filter element is arranged in the steel groove; the rubber sleeve is detachably arranged at the end part of the air inlet cylinder.
The portable sampling bag for the gas chromatograph comprises an air bag body, wherein the volume of the air bag body is 1-5L.
The portable sampling bag for the gas chromatograph comprises an air bag body and a rubber plug, wherein the air bag body is provided with an air outlet in the peripheral wall of one side, which is far away from an opening, of the air bag body, and the rubber plug is installed on the air outlet.
The portable sampling bag for the gas chromatograph is characterized in that the air bag body is a rubber air bag or a PVC air bag.
Foretell portable sampling bag for gas chromatograph, wherein, air inlet cylinder inner is provided with the internal thread, the rubber sleeve outside be provided with the external screw thread of internal thread looks adaptation, air inlet cylinder with the rubber sleeve passes through threaded connection.
The portable sampling bag for a gas chromatograph described above, wherein the cross-sectional area of the gas outlet is less than 1/5 of the cross-sectional area of the opening.
3. Advantageous effects
To sum up, the beneficial effects of the utility model reside in that:
(1) the utility model discloses an air filter core is installed at the air inlet position to the collection bag for chromatograph, can avoid the impurity in the natural atmosphere environment to get into the sampling bag to further ensure that the gas that contacts with the gas chromatograph is impurity-free, avoid the instrument of gas chromatograph to damage;
(2) the utility model discloses a chromatograph is with gathering bag portable, and the filter core is detachable construction, can pull down the washing, is suitable for the used repeatedly of gathering the bag, and whole gathering bag simple structure, easy and simple to handle, with low costs, the marketing of being convenient for.
Drawings
Fig. 1 is the utility model relates to a half-section of a portable sampling bag for a gas chromatograph.
Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
Referring to fig. 1, a portable sampling bag for a gas chromatograph comprises an air bag body 1 and a rubber sleeve 2; an opening 3 is formed in one end of the air bag body 1 along the axial direction, and the opening 3 extends along the axial direction of the air bag body 1 to form an air inlet cylinder 4; the air inlet cylinder 4 and the air bag body 1 are of an integral structure; a steel groove 5 is fixedly arranged on the inner side of the air inlet cylinder 4, and a filter element 6 is arranged in the steel groove 5; the rubber sleeve 2 is detachably arranged at the end part of the air inlet cylinder 4.
The volume of the airbag body 1 is varied from 1L to 5L according to different use purposes.
Airbag body 1 keeps away from opening one side perisporium is provided with gas outlet 7, just install the plug on the gas outlet 7, the size of gas outlet 7 just in time with the size adaptation of conventional gas chromatograph intake pipe, can adapt to different chromatograph intake pipes simultaneously through different adapters.
The air bag body 1 is a rubber air bag or a PVC air bag and has a long service life.
Preferably, an internal thread is arranged at the inner end of the air inlet cylinder 4, an external thread matched with the internal thread is arranged on the outer side of the rubber sleeve 2, and the air inlet cylinder 4 is connected with the rubber sleeve 2 through a thread.
