Abstract
The utility model discloses a kind of gas chromatogram gas sample injection device, it is characterized in that: six-way valve (3) is connected with water tumbler (2), sampling injector (1), gas source pipe (6) and gas chromatographic sample introduction mouth (7) by pipeline respectively, gas source pipe (6) and gas chromatographic sample introduction mouth (7) are connected to two interfaces that six-way valve (3) is adjacent, water tumbler (2) and sampling injector (1) are connected to two interfaces that six-way valve (3) is the most adjacent, the two interface connected is relative, remains two interfaces and is connected by quantitative loop (8).
Description
Technical field
This utility model relates to a kind of gas chromatogram gas sample injection device, belongs to laboratory paraphernalia field.
Background technology
Glass syringe direct injected and six-way valve sample introduction is mainly taked time at present with chromatographic gaseous sample
Two kinds of methods, wherein glass syringe sample introduction needs the airbag gathering gaseous sample to have corresponding pin hole sample point, and the method is held
Being easily caused the syringe needle blocking of glass syringe, simultaneously because gas syringe needle point is relatively thick relative to liquid sample feeding device, gas divides
The loss of gas chromatographic sample introduction dottle pin can be accelerated during analysis.General employing six-way valve sample introduction in the gas chromatogram be furnished with six-way valve,
Need to be connected the gas production mouth of airbag by pipe fitting with the injection port of six-way valve when sampling, then turn on airbag gas production valve also
Gas production bag is squeezed into the loading of row gaseous sample, because of technological reason in extrusion process, the gas production valve of many airbags
There is gas leak phenomenon in various degree, in the case of gas leakage, even if all gas squeezed in airbag can not guarantee quantitatively
Ring enters enough gaseous samples, devises this sampling device for this for solution the problems referred to above.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of gas chromatogram gas sample injection device, existing to solve
The deficiency of technology.
The technical solution of the utility model is: a kind of gas chromatogram gas sample injection device, six-way valve respectively by pipeline with
Water tumbler, sampling injector, gas source pipe connect with gas chromatographic sample introduction mouth, and gas source pipe and gas chromatographic sample introduction mouth are connected to six
Leading to two interfaces that valve is adjacent, water tumbler and sampling injector are connected to two interfaces that six-way valve is the most adjacent, and the two connects
Interface is relative, remains two interfaces and is connected by quantitative loop.
The connection pipe end of described sampling injector connects airbag joint.
The pipeline that connects of described sampling injector is respectively provided with check valve before and after the access point of sampling injector.
The beneficial effects of the utility model: this device takes syringe precisely to sample by six-way valve dress sample and sample introduction, no
There is the phenomenon of the syringe needle blocking of glass syringe, when airbag is sampled, airbag need not be extruded, only need push-and-pull syringe
Just sampling, reduces the infringement that airbag is caused by extruding, even if there is gas leak phenomenon in airbag, and bag of the most only need to gently calming the anger push-and-pull simultaneously
The most desirable enough gas sample of syringe are the worst to be full of, and the simultaneous quantitative ring port of export immerses to be had in hydrophone ware, by the product of bubble
Raw situation also can determine whether whole loading gas circuit UNICOM situation, it is simple to finds timely and effectively and solution problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation during this utility model sample introduction.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of gas chromatogram gas sample injection device, six-way valve 3 respectively by pipeline and water tumbler 2, take
Sample syringe 1, gas source pipe 6 connect with gas chromatographic sample introduction mouth 7, and gas source pipe 6 and gas chromatographic sample introduction mouth 7 are connected to clematis stem
Two interfaces that valve 3 is adjacent, water tumbler 2 and sampling injector 1 be connected to two interfaces that six-way valve 3 is the most adjacent, and the two connects
Interface relative, remain two interfaces and passes through quantitative loop 8 and connect.The connection pipe end of described sampling injector 1 connects gas
Bag joint 5.The pipeline that connects of described sampling injector 1 is respectively provided with check valve 4 before and after the access point of sampling injector 1.
Water tumbler 2: the port of export water tumbler of quantitative loop, the port of export of quantitative loop is put into water tumbler, is had bubble and produce when loading gas
Raw to show that water tumbler is normally put in pipeline connection, have bubble when loading gas and produce to show that pipeline connects normal.
Sampling sample introduction realizes process:
1, six-way valve is transferred to load sample state, as shown in Figure 1；
2, airbag joint connects airbag acquisition port；
3, gas production bag gas production valve is turned on；
4, pull out syringe and pushing syringe completes to fill sample process, during dress sample, water tumbler has bubble and produce；
5, sample introduction state is transferred to by six-way valve, as in figure 2 it is shown, make quantitative loop 8 be in gas chromatogram gas circuit, completes sample introduction.
That is: six-way valve is transferred to into sample state, as shown in Figure 2；Gas source pipe 6 connects with quantitative loop 8 one end；Gas chromatographic sample introduction mouth 7
Connect with quantitative loop 8 other end, form connecting pipeline；Turn on source of the gas air valve；Quantitative loop 8 is made to be in gas chromatogram gas circuit, complete
Become sample introduction.
