The simple device comprises a pressurizing device, a liquid supply device and a chromatographic column, and is characterized in that the liquid supply device is formed by a constant-pressure separating funnel. The utility model mainly solves the problems in the prior art that the pressurization operation and the liquid supply operation can not be completed at the same time, the eluting agent needs to be added frequently, and the eluting agent can not be loaded or controlled independently. Compared with the prior art, the device achieves the purposes of loading sufficient eluting agents in one step, ensuring continuous pressurization, liquid supply and elution and controlling the liquid supply speed without affecting pressurization. The structural design of the device is scientific and reasonable, the individual parts of the device are all commonly-used devices in labs and easy to operate, and extra special apparatuses are not needed. The device is suitable for laboratory teaching and scientific research as well as industrial production, and is worthy of being promoted.
Description
Technical field
The utility model relates to chemical substance separation and purification field, especially a kind of pressurized column chromatography device.
Background technology
Chromatographic technique is natural products laboratory, chemical laboratory, the requisite separation means of biology laboratory; Its principle is to utilize the difference of each component physical property; Multicomponent mixture is separated and method for measuring, and it comprises, and column chromatography, ply of paper are analysed, thin-layer chromatography, high performance liquid chroma-tography etc.Column chromatography is the most frequently used a kind of in laboratory, and it comprises normal pressure column chromatography, decompression column chromatography and pressurized column chromatography.Normal pressure column chromatography condition is the simplest, but because its internal pressure is not enough, can only use thick silica gel, and elution time is long.The decompression column chromatography relies on ambient pressure that each component in the mixture is eluted successively, but the solvent loss of using is big, and operation is frequent, and separating effect is undesirable.Pressurized column chromatography is a kind of reasonable method, only borrows impressed pressure that eluent is walked hurry up, and providing of pressure can be compressed air, and bulbs,double or little air pump are not only practiced thrift elution time but also good separating effect is arranged.But present pressurized column chromatography device is directly pressue device to be linked to each other with chromatographic column; Or passing through the liquid storage ball links to each other with chromatographic column, and the former will frequently add eluent, complex operation; Influence pressurized operation again: though the latter has the liquid storage ball can once lay in enough eluents; But must could lay in liquid together with chromatographic column, can not independently use, and in pressure process, leak eluent easily.
China's utility model patent has provided " a kind of controlled pressurization chromatography splitter " for No. 200820188701.2, it is characterized in that pressue device directly links to each other with chromatographic column, and chromatographic column one side has two arms to be connected with liquid-adding device; Also can liquid feeding in pressurization though can solve, it install complicacy, complex operation; And the lid of liquid-adding device and the piston on the arm exist the hidden danger of gas leakage; Lid is ejected by air pressure easily, not only influences experiment effect, and dangerous again.
Up to the present event does not see a kind of liquid feeding that can pressurize simultaneously, simple and easy safely and effectively pressurized column chromatography device simple to operate again yet.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of easy pressurized column chromatography device is provided, and possesses the disposable independent capacity eluent that adds, the liquid feeding wash-out that pressurizes continuously, and controlled liquid feeding speed does not hinder the characteristics of pressurized operation again.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of easy pressurized column chromatography device is characterized in that: be made up of pressue device, liquid-adding device and chromatographic column.Described pressue device is tightly connected through the port of tube connector and liquid-adding device; Liquid-adding device is made up of the constant voltage separatory funnel; This is the topmost characteristic of the utility model; The constant voltage separatory funnel both can add eluent in whole chromatography process, the passage that can be used as gas-pressurized again is the chromatographic column pressurization.The port of said liquid-adding device lower port and chromatographic column is tightly connected.Whole device air-tightness is good, can regulate the flow velocity of eluent in chromatographic column through the piston of chromatographic column lower end, regulates liquid feeding speed through the piston of constant voltage separatory funnel lower end, and the pressurization liquid feeding carries out simultaneously.
Compared with prior art, advantage of the utility model and beneficial effect are:
The utility model provides a kind of easy pressurized column chromatography device, can disposablely independently add the capacity eluent, the liquid feeding wash-out that pressurizes continuously, and controlled liquid feeding speed does not hinder pressurized operation again, has solved the difficult problem of frequent interpolation eluent.Scientific structure design is reasonable, and each several part all is the conventional instrument in laboratory, and is easy to operate, need not to be equipped with in addition specific apparatus, is applicable to breadboard teaching and scientific research and suitability for industrialized production, is worth emphasis to be promoted.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The structural representation of the utility model is shown in accompanying drawing 1, and a kind of easy pressurized column chromatography device is made up of pressue device 1, liquid-adding device 2 and chromatographic column 3.At first column chromatography silica gel and the silica gel that is mixed with sample are filled in the chromatographic column 3 on request; Again the eluent that modulates in advance of capacity is packed in the constant voltage separatory funnel 2 of predetermined; With constant voltage separatory funnel 2 and chromatographic column 3 butt joints; Constant voltage separatory funnel 2 and chromatographic column 3 are fixed on the iron stand simultaneously, keep the stability of whole device.Keep the piston on constant voltage separatory funnel and the chromatographic column to close this moment simultaneously, and the tube connector 11 with pressue device 1 closely is connected with constant voltage separatory funnel 2 again, begins pressurization, opens two-piston simultaneously and begin to add eluent and collect eluent.
According to aforesaid way, the continuous wash-out of liquid feeding of can realizing pressurizeing has simultaneously solved the difficult problem of frequent interpolation eluent again.
