The chromatographic column 1 is provided with scales, and the top end thereof is connected with the pressurizer 3; and the sample injector 2 is connected with the chromatographic column 1 by two branch pipes with pistons. The utility model provides a controllable pressurizing chromatographic separation column which is characterized by increasing eluting flow rate, being convenient to add eluate and eluting and separating for long time. The design of the chromatographic separation column can control usage of column packing, and also can accurately observe the usage of an eluting agent. The controllable pressurizing chromatographic separation column has simple use and convenient operation and is applicable to industrial production and laboratory use.
Description
Technical field
The utility model relates to the separation and purification field, is specifically related to a kind of chromatographic column.
Background technology
In daily laboratory experiment or industrial production, can use the post separation method usually, as every field such as industry, agricultural, medicine, scientific researches.The post separation method be kind simple, quick, sensitive, separate efficiently, method of purification.It is the glass tube of fill erectting with column packing that post is analysed separation process layer by layer, desires separator with a certain proportion of chemical mixing liquid wash-out, and this mixed liquor is called eluent, behind wash-out after a while, is separated into several parallel colour bands by a colour band.Its principle is by changing the polarity of eluent, the different separating substances of polarity being come, and elute sequentially, thereby reach effect of separating purification.But different because of column packing density and degree of absorption can be caused the too slow of sample separation, have influenced the efficient and the effect of separating, so many times, need take some measures, and as pressurization or method such as vacuumize separator can be separated fast.The method of quickening the chromatographic column separation at present mainly contains two kinds, a kind of is that the bottom of chromatographic column is fixed on the bottle,suction, utilize water circulating pump or vavuum pump to accelerate the flow velocity of eluent, thereby separate fast, but this class air extractor quantity of heat production is very big, the working time can not be long, so just prolonged the time that crosses pillar, and its lower end is fixed on the bottle,suction, also can influence to receive the liquid that elutes, inconvenient operation; Another is to adorn a pressue device on the top of pillar, but this device can hinder the operation of adding eluent again, both wastes time and energy like this, has also increased the danger coefficient of instrument damage.Do not see yet at present a kind of both can be for a long time, increase elution flow rate, the convenient again chromatography column device that adds eluent.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of controlled pressurization chromatography splitter is provided, and has the increase elution flow rate, the convenient eluent that adds, the characteristics that long-time wash-out separates.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of controlled pressurization chromatography splitter is made up of column type chromatographic column and transparent column type sample injector from bottom to top, and the upper end of chromatographic column is connected with pressurizer.
Above-mentioned chromatographic column is the column type pipe, and the lower end is provided with a piston, is used for receiving the solution that elutes; Bottom in chromatographic column inside has a husky core, but the bolster stake filler; Shaft has scale, can control the charge weight of filler, also can observe position and speed that each chromatograph elutes; Chromatographic column shaft upper end is provided with the arm of two band pistons, connects sample injector; There is an interface pillar upper end, is used for connecting pressurizer.
Above-mentioned sample injector is the column type transparent vessel, and the lower end is provided with two arms that have piston, and is connected with the chromatographic column upper end, can control the interpolation of eluent, when piston is opened, constitutes the container of a connection; The sample injector outside is provided with scale, can observe the consumption of eluent so intuitively, convenient record and calculating consumption; There is the lid of a ground its upper end.
Above-mentioned pressurizer is provided with knob and a pressurization interface of pressurization knob, a pressurization timer, connects a conduit on the interface, and the other end of conduit connects by the last end interface of chromatographic column, is convenient to pressurize.
Compared with prior art, the present invention has following beneficial effect:
The utility model provides a kind of controlled pressurization chromatography splitter, has the increase elution flow rate, the convenient eluent that adds, the characteristics that long-time wash-out separates.Chromatography is shared the design of post, can control the use amount of column packing, also can accurately observe the use amount of eluant, eluent.Use simply, easy to operate, be applicable to the use of industrial production and laboratory.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 1, controlled pressurization chromatography splitter is made up of column type chromatographic column 1 and transparent column type sample injector 2 from bottom to top, the upper end of chromatographic column 1 is connected with pressurizer 3.There is a piston 11 chromatographic column 1 lower end, is used for controlling receiving the liquid that elutes, and its interior lower end is provided with Sha Xin 12, but the bolster stake filler, and wall one side has scale 13, is convenient to observe the elution speed of each chromatograph.Two arms 21,23 that have piston 22 are up and down extended in the chromatographic column upper end, be connected in the wall and the bottom of sample injector 2, when piston 22 is opened, make chromatographic column 1 and sample injector 2 constitute the container of a connection, these sample injector 2 integral body are a glass transparent container, and its container itself is provided with scale 24, can observe the consumption of eluent so intuitively, convenient record and calculating consumption, there is the lid 25 of a ground its upper end.End interface 14 is connecting the conduit 34 of pressurizer 3 on the chromatographic column 1, pressurizer 3 is provided with pressurization knob 31, pressurization timer knob 32 and pressurization interface 33, what link to each other with interface 33 is conduit 34, and conduit 34 joins by end interface on the chromatographic column 1 14 and chromatographic column 1, is convenient to pressurization.
Method of operating: during use, earlier chromatographic column 1 usefulness column packing is installed, last sample, connect pressurizer 3 by Fig. 1, and all pistons are in closed condition, in sample injector 2, put into the eluent that has configured, open piston 22 and lid 25, add eluent slowly, when treating that eluent reaches the column packing height, cover lid 25, open piston 11, open the pressurization knob 31 of pressurizer 3 then, beginning is the pressurization wash-out slowly, carry out wash-out, can set the pressurization elution time by control pressurization timer knob 32, when the liquid level of the eluent in the chromatographic column 1 is lower than arm 23 according to the wash-out situation, pressure can be pressed into the eluent in the sample injector 2 in the chromatographic column by arm 21 by arm 23, need not the people during wash-out for adding eluent, eluted, receive for further analysis and research with container until chromatograph.
