Abstract
Carbon isotope analysis sample storage device in a kind of carbonate of dissolving, include casing, case lid, liquid nitrogen container, reagent bottle, valve, GORE TEX films, inlet non return check valve；Liquid nitrogen container and reagent bottle are placed in casing；Liquid nitrogen container is connected by conduit with reagent bottle, and valve is provided with the conduit；Reagent bottle top is provided with GORE TEX films；Liquid nitrogen container and reagent bottle are laid in casing；Hole is provided with the top of the wall of casing, hole lining has set inlet non return check valve；Case lid is connected by hinge with casing.Low temperature and inert atmosphere provided by the utility model inhibit the growth of microorganism, avoid sample from going bad；Malleation atmosphere is built and avoids outside air and entered so as to influenceing the carbon isotope composition of carbonate in sample；Make gas outflow in case using inlet non return check valve and avoid ambient atmos from flowing into, it is suppressed that hypertonia in case, and influence the air-tightness of casing.The utility model is simple in construction easy to utilize.
Description
Technical field
Carbon isotope analysis sample in glaciology field, in particular to a kind of carbonate of dissolving is the utility model is related to deposit
Storage device.
Background technology
The material long term such as rock and empty gas and water, carbon dioxide, the chemical reaction of complexity occurs, produces novel substance
Process is referred to as chemical weathering, and chemical weathering process is to CO in air2Long-term forever continuous consumption process, in 1000000 years chis
Global climate change is adjusted on degree.Research at present shows the CO in the chemical weathering process consumption air of two rocks2：Silicic acid
The chemical weathering of rock and carbonatite.On million annual time scales, the CO of carbonatite weathering consumption2It can be sunk by carbonatite in ocean
The CO discharged during product2Offset, and the chemical weathering process of Silicate Rocks consumes the CO in air only2, it is the important mistake for influenceing carbon cycle
Journey.Therefore the chemical weathering of quantitative analysis Silicate Rocks and carbonatite is most important to research global carbon process.Study water body
Stable carbon isotope ratio can more accurately judge the carbonate source dissolved in water body in the carbonate of middle dissolving.It is but big
Ubiquitous CO in gas2It can be exchanged with the carbonate in testing sample, it is same so as to influence the carbon of carbonate in sample to be analysed
The plain ratio in position.Given this carbon isotope analysis sample storage device in a kind of carbonate of dissolving is devised, for short-term storage
Sample, sample is avoided to be polluted from test is collected by outside air.
Utility model content
In view of it is above-mentioned, in order to overcome the shortcomings of the prior art, the purpose of this utility model aims to provide a kind of dissolving
Carbonate in carbon isotope analysis sample storage device.
Technical scheme is used by the utility model solves its technical problem：
Carbon isotope analysis sample storage device in a kind of carbonate of dissolving, includes casing, case lid, liquid nitrogen container, examination
Agent bottle, valve, GORE-TEX films, inlet non return check valve；Liquid nitrogen container and reagent bottle are placed in casing；Liquid nitrogen container passes through conduit and examination
Agent bottle is connected, and valve is set on the conduit；Reagent bottle top is provided with GORE-TEX films；The top of box body wall is provided with hole,
And inlet non return check valve is set in hole lining；Case lid is connected by hinge with casing.
Interface between casing and case lid is provided with sealing ring.
Inlet non return check valve is laid in casing away from GORE-TEX films apart from farthest.
The advantages of the utility model and beneficial effect are：
The utility model provides low temperature and inert atmosphere so as to suppress the growth of microorganism, has built malleation atmosphere and has avoided
Outside air enters so as to influence the carbon isotope composition of carbonate in sample；Gas in case is flowed out using inlet non return check valve
And ambient atmos are avoided to flow into, it is suppressed that hypertonia in case, and the air-tightness of casing is influenceed, the utility model can not only be used
Carry out carbon isotope sample to be analysed in the carbonate of short-term storage dissolving, avoid product in transportation by air pollution, can also
As ice sample melt be water sample when storage device, sample can be avoided to be polluted in melting process by outside air.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Illustrate to be described further the utility model below in conjunction with the accompanying drawings：
As shown in figure 1, carbon isotope analysis sample storage device in a kind of carbonate of dissolving, includes casing 1, case lid
2nd, liquid nitrogen container 3, reagent bottle 4, valve 5, GORE-TEX films 6, inlet non return check valve 7.
Liquid nitrogen container 3 and reagent bottle 4 are placed in casing 1；Liquid nitrogen container 3 is connected by conduit with reagent bottle 4, is provided with conduit
Valve 5.
The top of reagent bottle 4 is provided with GORE-TEX films 6.
The top of the wall of casing 1 is provided with hole, and inlet non return check valve 7 has been laid in the hole.
Case lid 2 is connected by hinge with casing 1.
Embodiment
After sample is placed in casing 1, valve 5 is opened, the nitrogen for making to evaporate in liquid nitrogen container 3 enters reagent by conduit
Bottle 4, NaOH solution is filled with reagent bottle 4, NaOH solution can absorb CO remaining in nitrogen2Gas；On the top of reagent bottle 4
Provided with GORE-TEX films 6, GORE-TEX films 6 only allow gas by, so can only make nitrogen enter casing 1 in, and
Avoid NaOH solution and enter casing 1；Nitrogen enter casing 1 in after pass through inlet non return check valve 7 flow out casing 1, inlet non return check valve 7
It is laid in casing 1 away from GORE-TEX films 6 apart from farthest, so can fully discharge air makes nitrogen be full of casing 1；It is logical
Cross hinge case lid 2 is fixed on casing 1, the interface of casing 1 and case lid 2 is equipped with sealing ring, to maintain the gas in casing 1
Close property.
