Abstract
The invention discloses a sectional type glass chromatographic column comprising a column body (1) and characterized in that the column body (1) comprises a bottom column (2), a top column (3) and a plurality of middle columns (4), wherein the inner side wall of the bottom column (2) is sealed and connected with the outer side walls of the middle columns (4); the inner side walls of the middle columns (4) are sealed and connected with the outer side wall of the top column (3); and the top end of each middle column (4) is open, and a permeable ventilated first baffle (5) is arranged at the bottom end. The sectional type glass chromatographic column provided by the invention is simple in structure and reasonable in design, a ribbon can be taken out, the sample loading capacity is large, the upper surface of a packing is prevented from being washed up, a used packing is taken out easily, and the sectional type glass chromatographic column is suitable for being widely popularized and applied in laboratories.
Description
Technical field
The present invention relates to a kind of segmented glass column, belong to chemical experiment consumptive material technical field.
Background technology
Current glass column is integral type, be a whole glass column up and down with import and outlet, the dress column method of this kind of glass column is divided into dry method and wet method, dress column packing is silica gel, resin or polyamide etc., no matter dry method or wet method, the upper surface of filler must be smooth, and current glass column installs rear upper surface, can both guarantee smooth, but being easy to the upper surface of filler to rush when eluting solvent is added in import, even placed cotton at the upper surface of filler, be also difficult to avoid this problem, be that current glass column is without flush-prevention function, in addition, the glass column of integral type is because import is little, and the filler using is difficult for pouring out from import, therefore existing glass column exists, is difficult for taking out the problem of using filler, the most important thing is, current chromatographic column, after separator well colour band, can not be taken out colour band, can only at leisure colour band be rinsed with eluting solvent, the method that colour band can be taken out at present still rests on the method that lamellae launches rear scraper plate, can not realize by column chromatography.
Summary of the invention
Technical problem to be solved by this invention is, providing a kind of can take out colour band, and volume containing the sample is large, prevents that filler upper surface from having rushed and easily takes out the segmented glass column of using filler.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of segmented glass column, comprise: cylinder, it is characterized in that: described cylinder comprises foundation, fore-set and some intermediolateral columns, described foundation madial wall is connected with intermediolateral column lateral wall is airtight, described intermediolateral column madial wall is connected with fore-set lateral wall is airtight, described intermediolateral column top end opening, bottom is provided with the first baffle plate of water-permeable and air permeable.
The top of described fore-set is provided with import, and bottom is provided with the second baffle of water-permeable and air permeable.
The bottom of described foundation is provided with the 3rd baffle plate and outlet of water-permeable and air permeable, and described the 3rd baffle plate is positioned at the top of described outlet.
Described foundation madial wall, intermediolateral column lateral wall and lateral wall, fore-set lateral wall are provided with frosted layer.
On the lateral wall of described intermediolateral column and foundation, be provided with dry volume graduation mark and humid volume graduation mark, described humid volume graduation mark be positioned at described dry volume graduation mark below and with the position of described the first baffle plate (5) bottom surface level mutually.
The graduation mark that packs filler stem into when described dry volume graduation mark is dry column-packing, the graduation mark that packs wet filler the into when graduation mark after filler stem compacting when described humid volume graduation mark is dry column-packing and wet method dress post.
A kind of segmented glass column that invention provides, during use, in foundation and intermediolateral column, pack filler into successively, in the intermediolateral column being connected with fore-set, pack filler and sample to be separated into, then connect successively foundation, intermediolateral column and fore-set, after fixing, can rinse, when the obvious colour band of separator well, treat that eluting solvent drains off, can take out each section of colour band, then after utilizing organic reagent to extract stripping colour band, filtration can obtain the compound in colour band, the function that colour band is taken out in the column chromatography that glass column of the present invention is realized, large compared with conventional lamellae chromatography method sample separation amount, alleviated widely separated workload, improved operating efficiency, saved experimental resources, in addition, because fore-set lower surface has second baffle, protect the filler upper surface of intermediolateral column, therefore filler upper surface can not rushed, guaranteed the smooth of filler upper surface, make sample separation to be separated effective, colour band is even, finally, segmented glass column of the present invention, because foundation, intermediolateral column, fore-set are separated, after finishing using, only need outward winding successively, with the filler of crossing, can directly be poured out by the upper surface of foundation and intermediolateral column, the filler of using that has solved existing chromatographic column is difficult for the problem of taking out.A kind of segmented glass column provided by the invention, simple in structure, reasonable in design, colour band can be taken out, volume containing the sample is large, prevents that filler upper surface from having rushed and easily takes out and used filler, is adapted at laboratory wide popularization and application.
