Description

Closed phase chromatography-use flowing phase apparatus for placing
Technical field
The utility model relates to a kind of closed phase chromatography-use flowing phase apparatus for placing.
Background technology
The high performance liquid chromatography that holds at present commonly used all is the open type that communicates with air with the solvent bottle of flowing phase; As shown in Figure 1; Open type flowing phase apparatus for placing is for common flowing phase commonly used; Be not much affected, but for be prone to absorb Carbon Dioxide in Air and influence flowing phase (particularly pH value shows the flowing phase of alkalescence), the volatile flowing phase (the organic facies proportion is bigger) and the flowing phase that contains the excitant component of its pH value, significant limitation is arranged.
Open type flowing phase apparatus for placing can't solve flowing phase at all and absorb the influence of Carbon Dioxide in Air to its pH value; Particularly pH value shows the flowing phase of alkalescence; And this type flowing phase also can run in the liquid phase assay method, and this necessitates with regard to the appearance that makes closed phase chromatography-use flowing phase apparatus for placing.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of closed phase chromatography-use flowing phase apparatus for placing being provided.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of closed phase chromatography-use flowing phase apparatus for placing, it comprises the airtight container that holds phase chromatography-use flowing phase, airtight container links to each other with the feed tube that is connected liquid phase systems, and an end of this feed tube extend in the flowing phase in the airtight container; Also be provided with two ventilation devices on the sealing container, all have the venting cavity of the upper space of flowing phase liquid level in the communication seals container on these two ventilation devices; One of them ventilation device is provided with valve, and another ventilation device is communicated with soft bag, also is provided with a blow vent that has valve on the soft bag.
The end that the upper space of flowing phase liquid level is communicated with in venting cavity and the airtight container is an exhaust outlet, the exhaust outlet of one of them ventilation device on the short transverse near the liquid level of flowing phase; The exhaust outlet of another ventilation device on the short transverse away from the liquid level of flowing phase.
The junction of said soft bag and ventilation device is provided with valve.
The end that said feed tube extend in the said airtight container is provided with solvent filter.
Said airtight container is made up of solvent bottle and bottle stopper, perhaps is made up of the solvent Bottle and bottle cap.
One of them ventilation device is: it is located at the side of solvent bottle upper end, and is integrally formed structure with solvent bottle bottle wall; Bottle stopper or bottle cap are provided with two through holes; Another ventilation device is: pass the breather pipe of one of them through hole, the end that this breather pipe is positioned at solvent bottle is an exhaust outlet, this exhaust outlet on the short transverse near the liquid level of flowing phase; Said feed tube passes another through hole.
Bottle stopper or bottle cap are provided with three through holes, and one of them ventilation device is: pass the breather pipe of one of them through hole, an end that is positioned at solvent bottle of this breather pipe is an exhaust outlet, this exhaust outlet on the short transverse near the liquid level of flowing phase; Another ventilation device is: pass the breather pipe of another through hole, an end that is positioned at solvent bottle of this breather pipe is an exhaust outlet, this exhaust outlet on the short transverse away from the liquid level of flowing phase; Said feed tube passes the 3rd through hole.
Between above-mentioned solvent bottle and bottle stopper or the bottle cap, and all be tightly connected between the through hole on feed tube and breather pipe and bottle stopper or the bottle cap, guarantee to form on the whole an airtight container.When breather pipe when through hole passes, the glass tube that breather pipe can adopt both ends open to have venting cavity is processed.When breather pipe is positioned at the side of solvent agent upper end; Breather pipe is that the bottle wall of solvent bottle outwards stretches the structure that forms tubulose; Itself and solvent bottle itself are structure as a whole, and also can regard the part of solvent bottle as, at this time; Because the exhaust outlet of this breather pipe flushes with the solvent bottle inwall and is positioned at the side on the solvent bottle, so also be exhaust outlet on the short transverse near the liquid level of flowing phase.
Soft bag is processed (such as polypropylene, Kynoar etc.) by the macromolecular material of organic solvent-resistant, acid and alkali-resistance, can inflated with nitrogen between its citadel etc. inert gas.
With those skilled in the art's understanding, airtight container should be provided with one and can flowing phase be contained into the opening in (or pouring into) airtight container, and can open the lid with seal closure, adds bottle stopper or bottle cap such as solvent bottle.
Owing to the difference that is sealed with of inert gas and air, upwards emptying gas method is used for the density inert gas bigger than atmospheric density, and emptying gas method is used for the density inert gas littler than atmospheric density downwards.The inert gas here refers to and comprises rare gas or nitrogen.When inert gas is nitrogen; Because density of nitrogen is littler than atmospheric density; So adopt downward emptying gas method, be air inlet one end with exhaust outlet ventilation device near the liquid level of flowing phase on the short transverse, with exhaust outlet on the short transverse away from the ventilation device of the liquid level of the flowing phase end of giving vent to anger.
Its basic method for using is: flowing phase is contained in the airtight container of this device; Behind the ultrasonic degas; (with bottle cap or bottle stopper fixing seal on solvent bottle) connected valve between valve, soft bag and the airtight container and the valve on the breather pipe on the blow vent, charges into inert gas (when inert gas is nitrogen; Selecting exhaust outlet ventilation device near the liquid level of flowing phase on the short transverse is air inlet one end); After waiting to replace the air in the device seal area, stop to charge into inert gas, close the valve on the valve and breather pipe on the blow vent then.Then, carry out the operation of liquid phase, this moment, flowing phase got in the liquid chromatographic system through feed tube; Flowing phase liquid level in the airtight container descends; It is big that the space of liquid level top becomes, and the inert gas that stores in the soft bag gets in the space in the sealing container and since soft bag neither the container of fixed volume; There is not elasticity, so can protect the airtight container internal gas pressure constant yet.
Compared with prior art; The beneficial effect of the utility model is; Adopt this device, can solve flowing phase and absorb carbon dioxide in air and the flowing phase pH value is changed, can solve the volatilization of organic component in the flowing phase again and the ratio of each component of flowing phase is changed; Huaihe River is really reliable more to make liquid phase measure the result, can reduce the infringement to environment and human body of organic solvent and excitant component simultaneously.
