Description
Technical field
The present invention relates to a kind of experimental provision, is particularly used for the experimental provision for storing liquid isotope standard.It is applicable
In liquid
The storage of isotope standard, facility can be provided for subsequent experimental.
Background technology
For storing the experimental provision of liquid isotope standard, as the term suggests it is to be used to store work standard specimen（Water）To be follow-up
Experiment provides facility.The storage of work standard specimen is all increasingly paid attention in many researchs now, and is used to store liquid isotope standard
Experiment
The selection and improvement of device are to the standard specimen that works（Water）Storage validity and security there is vital effect.
At present, the storage liquid isotope standard of use is mostly narrow-mouthed bottle, and the extraction and preservation of its work standard specimen are mostly
Separated,
Extraction in actual use be present has the defects of bubble, poorly sealed close.
The content of the invention
It is an object of the invention to provide a kind of experimental provision for being used to store liquid isotope standard, it can overcome
There is the deficiency of technology, integrate extraction and store function, work standard specimen can be extracted simultaneously（Water）, it is sealed, and can be straight
Use is connect, can not only be greatly enhanced conventional efficient, and with the advantages of simple to operate, cost is cheap.
Its solution is：Piston and piston cylinder stationary fit are tightly connected, in being provided with passage, passage rubber on piston
Leather plug is connected with vent seal.Inlet tube and outlet are disposed with piston cylinder, in being connected with inlet connecting branch on inlet tube,
And set fluted on inlet tube, import sealed rubber plug is embedded with groove, for being closing and sealing off inlet tube, in outlet
Interior setting exit seal rubber stopper.
The present invention uses above-mentioned technical proposal, due to being provided with passage on piston and having the sealing of passage rubber stopper,
Shed gas available for standing.And inlet tube and outlet are disposed with piston cylinder, and inlet tube and outlet use import
Pipe and the sealing of outlet rubber stopper, and inlet connecting branch is connected with inlet tube, it can not only avoid the suspension in air
The entrance of matter, but also the convenient various devices of connection, it is easy to use.The present invention has extraction concurrently with store function in one, can be with
Extract work standard specimen simultaneously（Water）, it is sealed, and can directly use, conventional efficient can not only be greatly enhanced, but also have
There is rational in infrastructure, firmly, simple to operate, practical, the advantages of cost is cheap.
Brief description of the drawings
Fig. 1 is for the structural representation main view profile for the experimental provision for storing liquid isotope standard.
Fig. 2 is for the top view for the experimental provision for storing liquid isotope standard.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
It is glassware, in glass infuser in Fig. 1, Fig. 2（4）Interior stationary fit is sealedly connected with piston component（1）, in piston
Component（1）On be provided with two passages（3）, each passage（3）In be sealedly connected with passage rubber stopper（2）.Glass infuser
（4）On be provided with the glass outlet pipe on the left side glass inlet pipe being arranged symmetrically and right side, in being connected with glass inlet pipe
Import rubber tube（5）, and set in glass inlet pipe fluted, it is embedded with import sealed rubber plug in groove（6）, for closing
Close simultaneously seal glass inlet tube.In setting exit seal rubber stopper in glass outlet pipe（7）.
The sampling and storage of isotope work standard specimen：When extracting work standard specimen water sample, pass through two passage rubbers first
Plug（2）With outlet rubber stopper（7）By two passages（3）With the glass exit seal of tube, import sealed rubber plug is then extracted（6）
To the height of its own half, and by import rubber tube（5）It is connected with work standard specimen water sample to be extracted, then pulls up piston
（1）, extract isotope work standard specimen concrete water quality and account for glass infuser（4）Behind the 2/3 of volume, again import sealed rubber plug（6）
Bottom portion of groove is pressed into, is closing and sealing off glass inlet pipe.Then, two passage rubber stoppers are extracted（2）, and push down on work
Plug（1）, until glass infuser（4）Bubble in interior work standard specimen water sample, pass through two passages（3）It is expelled in air, and
There is a small amount of liquid to overflow passage（3）, now, at once by two passage rubber stoppers（2）Again respectively by corresponding two ventilations
Hole（3）Sealing, you can complete the sampling and storage of isotope work standard specimen.
The extraction and demarcation of isotope work standard specimen：By sampler（Extract the instrument of work standard specimen in laboratory）Injection needle
Head, sampler injection needle is inserted and penetrates outlet rubber stopper（7）, the sampler piston of manipulation sampler injection needle, from
Glass infuser（4）Interior extraction samples and the work standard specimen water sample of storage to required capacity.Due in extraction isotope work mark
During sample water sample, piston（1）It can decline, piston with the movement of sampler piston（1）Lower surface all the time with glass infuser
（4）Interior extraction sampling and the work standard specimen water sample face stored are in sealing contact, therefore, in the extraction process of isotope work standard specimen
Bubble will not be produced.Then sampler syringe needle is extracted, the isotope work standard specimen water sample in sampler is sent into the same position of high accuracy
Quality spectrometer, the deuterium and the isotopic ratio of oxygen 18 of the standard specimen that worked using international standard sample Accurate Determining, by the isotopic ratio
The label paper is simultaneously pasted glass infuser by write-in label paper（4）On wall.
The extraction and use of work standard specimen：Operating procedure is identical with " extraction and demarcation of work standard specimen ", and difference exists
It need not again determine in the isotopic ratio of this work standard specimen, but directly read from the label paper on the wall of glass piston cylinder 4.
The injector that work standard specimen after extraction can be sent into isotope mass spectrometer is stand-by.
Due to having work standard specimen liquid in this container, when not in use, the container should be positioned over the bigger close of lucifuge
Seal in container, the SOLUTION PROPERTIES for being advantageous to work standard specimen is more preferably kept.
