Abstract

The utility model discloses a kind of chromatographic apparatus, including container body and lid, lid and container body combine the inner chamber to be formed and accommodate chromatographic solution, it is characterized in that, passage is formed on the lid, the both ends open of passage is respectively communicated with inner chamber and the external world, sealing-plug is installed on passage, there is a clamp structure that can clamp chromatographic paper on the bottom surface of sealing-plug, benefit of the present utility model is, when being put into chromatographic paper, lid need not be opened, only need to open the smaller sealing-plug of bore, chromatographic paper is clamped on the clamp structure of sealing-plug bottom surface, and sealing-plug is buckled on passage rapidly, because passage is formed on lid, its bore is less than the opening bore of container body, necessarily reduce the volatilization of chromatographic solution atmosphere in inner chamber, the particularly very hour of the bore design of passage, reduce the positive effect of atmosphere volatilization.

Description

A kind of chromatographic apparatus

Technical field

A kind of experimental facilities is the utility model is related to, specifically a kind of chromatographic apparatus.

Background technology

Chromatographic apparatus is used exclusively for the container that chromatographic paper carries out chromatography assay, usually by with holding chromatographic solution inner chamber Vessel and lid composition, lid be buckled in the opening of vessel, and vessel forms sealing inner chamber.It is being put into Before chromatographic paper, the chromatographic solution volatilization in inner chamber, chromatographic solution atmosphere is formed, until atmosphere is kept in critical value, that is, inner chamber Chromatographic solution concentration reaches balance, chromatographic solution is no longer volatilized.So, then by chromatographic paper it is put into chromatographic solution, keeps the standard of chromatography True property.But during practical operation, the process of chromatographic paper is put into opening lid, chromatographic solution atmosphere can be destroyed, influence chromatographic data.Separately Outside, one end of chromatographic paper needs to immerse in chromatographic solution, and the length of chromatographic paper immersion chromatographic solution part there are certain requirements.In order to Ensure that the distance of chromatographic paper intrusion chromatographic solution is moderate, it usually needs range estimation adds the height of the chromatographic solution of vessel, by warp Test the amount for determining to add chromatographic solution, it is difficult to complete the matching of chromatographic paper and chromatographic solution.

Utility model content

The utility model provides a kind of chromatographic apparatus, solves when being put into chromatographic paper, makes chromatographic solution atmosphere in zone of reasonableness The technical problem of change, experimental data will not be significantly affected, improve the accuracy of data analysis and comparison property.

In order to solve the above-mentioned technical problem, the utility model uses following scheme：

A kind of chromatographic apparatus, including container body and lid, lid and container body combine the inner chamber to be formed and accommodate chromatographic solution, its It is characterised by, passage is formed on the lid, and the both ends open of passage is respectively communicated with inner chamber and the external world, sealing is installed on passage Fill in, there is a clamp structure that can clamp chromatographic paper on the bottom surface of sealing-plug.

Compared to the prior art, benefit of the present utility model is, when being put into chromatographic paper, without opening lid, it is only necessary to The smaller sealing-plug of bore is opened, chromatographic paper is clamped on the clamp structure of sealing-plug bottom surface, and rapidly will sealing Plug is buckled on passage, because passage is formed on lid, its bore is less than the opening bore of container body, necessarily reduces inner chamber middle level The very hour of the bore design of the volatilization of liquid atmosphere, particularly passage is analysed, reduces the positive effect of atmosphere volatilization.

An embedded opening up vessel, the outer peripheral face of vessel are fitted on the inner peripheral surface of inner chamber in the inner chamber, device The cavity of sealing is formed between the bottom surface of ware and the bottom surface of inner chamber, a feed pipe is installed on container body, one end of feed pipe is opened Mouth connects with cavity, and another end opening passes in and out for liquid.

A handle for carrying o-ring is formed on the top surface of the sealing-plug.

Cross-sectional area at the passage lowest calibre is 1/5 of the area at container body opening lowest calibre.

One row's graduation mark is set on the wall of the container body.

Brief description of the drawings

Fig. 2 is the sectional view (sealing-plug opening) of another state corresponding with Fig. 1

Fig. 3 is the sectional view of one embodiment after improving.

Fig. 4 is the schematic diagram of liquid in corresponding with Fig. 3 removal chromatographic solution and cavity.

Reference

1 handle, 2 sealing-plugs, 3 lids, 4 inner chambers, 5 container bodies, 6 chromatographic solutions, 7 passages,

8 chromatographic papers, 9 vessel, 10 chromatographic solutions, 11 feed pipes, 12 cavitys, 13 graduation marks.

Embodiment

The utility model is elaborated with reference to the accompanying drawings and examples.

Such as Fig. 1 and Fig. 2, a passage 7, the lower ending opening communication with cavity 4 of passage 7, passage 7 are formed among lid 3 Upper end open connection it is extraneous, a sealing-plug 2 is installed on passage 7.7 preferable circular in cross-section of passage, sealing-plug 2 is therewith Matching.Should possess good sealing between sealing-plug 2 and passage 7.Therefore, forming face between sealing-plug 2 and passage 7 can be made The larger contact surface of product, improves sealing.Such as Fig. 1, inclined plane is formed between sealing-plug 2 and passage 7, contact surface can be effectively improved Product.The lower end of sealing-plug 2 has a clamp structure, and the clamp structure is used to clamp chromatographic paper 8, such as Fig. 3.

In addition, the cross-sectional area at the lowest calibre of passage 7 is 1/5 of the area at the opening lowest calibre of container body 5, size It is moderate.

During operation, lid 3 is first opened, the injection chromatographic solution 6 into inner chamber 4, then cover lid 3 (now sealing-plug 2 is sealed in On passage 7), hang on, until forming stable chromatographic solution atmosphere in inner chamber 4.Next, sealing-plug 2 is quickly opened, by layer Folder is analysed on clamp structure, quickly sealing-plug 2 is buckled on passage 7, chromatographic paper is goed deep into chromatographic solution.

Sealing-plug 2 is affectedly bashful for convenience, and the handle 1 with o-ring is formed on sealing-plug 2.

Such as Fig. 3 and Fig. 4, go deep into accurately adjust chromatographic paper 8 in chromatographic solution 6, an embedded vessel 9, layer in inner chamber 4 Analysis liquid 6 is contained in vessel 9, the outer peripheral face of vessel 9 and the inner peripheral surface fitting of inner chamber 4, makes the bottom surface of vessel 9 and the bottom surface of inner chamber 4 Between form the cavity 12 of sealing, feed pipe 11 is arranged on the wall of inner chamber 4, the one end open connection cavity 12 of feed pipe 11, Another end opening can connect with solution feed pump etc., pass in and out liquid.Specifically action process is：When the liquid level for needing rise chromatographic solution 6 Highly, liquid 10 can be poured into cavity 12, liquid 10 extrudes vessel 9 and moved up, and raises the liquid level of chromatographic solution 6；Conversely, Outside output liquid 10, can decline the liquid level of chromatographic solution 6.

Such as Fig. 4, as a further improvement, solving the problems, such as to facilitate reading layer to analyse liquid level scale, on the wall of container body 5 One group of graduation mark 13 is also marked, improves detection efficiency of the present utility model and the degree of accuracy.
