Description
Technical field
A kind of chromatographic column is the utility model is related to, particularly a kind of chromatography column apparatus of automatic liquid-feeding.
Background technology
At present when separating compound using chromatographic column, it is necessary to frequently add eluant, eluent, sometimes eluant, eluent addition is too late
When cause pillar dry and cracked, influence test separating effect.The utility model solves existing chromatographic column and existed in experimentation
Cumbersome, time-consuming and laborious problem.It is easy to wash out sample layer even packing layer when adding eluant, eluent, causes separating effect
Very poor, the utility model filling opening uses hole shower nozzle, alleviates liquid feeding impulse force, keeps the complete of filler in chromatographic column and sample layer
Property, filler and sample plane will not be destroyed, improves experiment separating effect.Chromatographic column of the present utility model realizes automatic liquid-feeding
Function, it is simple to operate, it is time saving and energy saving；Chromatographic column and liquid storage bottle are in sealing state in the utility model, prevent eluant, eluent from waving
Hair pollution environment.Catheter recoverable medical infusion lines, laboratory are turned waste into wealth in the utility model, prevent from polluting ring
Border, save resource.
Utility model content
The utility model purpose is to provide a kind of chromatography column apparatus of automatic liquid-feeding, is asked with solve to propose in background technology
Topic.
In order to solve the above technical problems, the utility model provides a kind of chromatography column apparatus of automatic liquid-feeding, including liquid storage
Bottle, catheter, chromatographic column, the liquid storage bottle top entry are provided with sealing-plug, and the liquid storage bottle outlet at bottom is provided with piston, described
Catheter and airway tube are provided with piston, described catheter one end is connected with liquid storage bottle outlet at bottom, its other end and chromatographic column
Top entry connection, be provided with hole piston at the top of the chromatographic column.
Preferably, the sealing-plug, piston, hole piston are rubber stopper or glass stopper with holes.
Preferably, the catheter is provided with dropping funnel and adjusting control valve.
Preferably, porous plug-hole shower nozzle is provided with below the hole piston, the porous nozzle top and drain pipe end
Portion connects.
Preferably, valve is provided with the chromatographic column outlet at bottom.
The utility model the same as compared with chromatographic column is used, there is following advantage at present：When separating compound, it is not necessary to frequently add
Add eluant, eluent, avoid eluant, eluent addition from causing pillar dry and cracked not in time, influence to test separating effect.Solves existing chromatographic column
Cumbersome present in experimentation, time-consuming and laborious problem.Using big liquid storage bottle, eluant, eluent is added without frequent,
Without constantly guarding, efficiency is improved.In addition frequent liquid feeding easily washes out sample layer even packing layer, causes separating effect very poor；
Filling opening uses porous nozzle, alleviates liquid feeding impulse force, keeps the integrality of the filler and sample layer in chromatographic column, will not destroy and fill out
Material and sample plane, improve experiment separating effect.Chromatographic column of the present utility model realizes the function of automatic liquid-feeding, operation letter
It is single, it is time saving and energy saving；Chromatographic column and liquid storage bottle are in sealing state in the utility model, prevent eluant, eluent volatilization pollution environment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is further described with reference to embodiment, not therefore by this reality
It is limited in new among described scope of embodiments.
As shown in figure 1, a kind of chromatography column apparatus of automatic liquid-feeding, including liquid storage bottle 1, catheter 3, chromatographic column 2, liquid storage bottle
1 top entry is provided with sealing-plug 9, and the outlet at bottom of liquid storage bottle 1 is provided with piston 7, is provided with catheter 3 and airway tube 4 in piston 7, leads
Liquid pipe 3 is provided with dropping funnel 5 and adjusting control valve 6.The one end of catheter 3 is connected with the outlet at bottom of liquid storage bottle 1, its other end and chromatography
The top entry connection of post 2, the top of chromatographic column 2 are provided with hole piston 21, and the lower section of hole piston 21 is provided with porous plug-hole shower nozzle 8,
The top of porous nozzle 8 is connected with the end of catheter 3.Sealing-plug 9, piston 7, hole piston 21 are rubber stopper or glass with holes
Plug.Valve 22 is provided with the outlet at bottom of chromatographic column 2.
Its operation principle is：The lower end valve 22 of chromatographic column 2 is closed before liquid feeding, eluant, eluent adds liquid storage bottle by sealing-plug 9
1, pass through catheter 3 from the bottom of liquid storage bottle 1（The band connecting tube of control valve 6）Into chromatographic column 2, after the completion of liquid feeding, chromatographic column 2 is opened
Lower end valve 22, it is complete by the roller on adjusting control valve 6 come coutroi velocity by dropping funnel 5 it can be seen that liquid is at the uniform velocity lower drips
Into liquid feeding.
Liquid storage bottle 1 can be selected that bottle is with a scale, the convenient volume for measuring eluant, eluent, be easy to change during gradient elution.Liquid storage
Bottle 1 should be placed in the platform higher than chromatographic column 2 and go out, and because liquid level high pressure is powerful, contribute to eluant, eluent to flow out.The upper and lower side of liquid storage bottle 1
Mouth band plug, lower end is provided with airway tube 4, makes liquid at the uniform velocity low by Action of Gravity Field, be arranged such, prevent the pollution that evaporates
Environment.Chromatographic column 2 is glass column, and lower end is matched somebody with somebody polytetrafluoroethylene (PTFE) plug, is arranged such, anticorrosion, service life length, application
Extensively.Catheter 3 uses medical infusion lines, and woven hose is recycled, is arranged such, anticorrosion, and service life length is easy to use,
Save resource.
The lower end of catheter 3 connects porous nozzle, is arranged such, and alleviates liquid feeding impulse force, keeps filler and sample in chromatographic column 2
The integrality of product layer, filler and sample plane will not be destroyed, improve experiment separating effect.
Finally it is pointed out that above embodiment is only the more representational example of utility model.Obviously, this reality
Above-mentioned embodiment is not limited to new, there can also be many deformations.Every foundation the technical essence of the utility model pair
Any simple modification, equivalent change and modification that above embodiment is made, it is considered as belonging to guarantor of the present utility model
