Abstract
The utility model discloses a multi-segment chromatographic column which comprises a primary liquid storage bottle and a plurality of secondary liquid storage bottles, wherein the secondary liquid storage bottles are connected with the primary liquid storage bottle; throttle valves are arranged at the bottoms of the primary liquid storage bottle and the secondary liquid storage bottles; stuffing columns are arranged between the primary liquid storage bottle and the secondary liquid storage bottles as well as between the secondary liquid storage bottles; T-shaped three-way pipes are arranged below the stuffing columns; a three-way valve is arranged on each T-shaped three-way pipe; a solvent injection port is arranged on each secondary liquid storage bottle; a last-segment stuffing column is arranged below the last secondary liquid storage bottle; and a valve is arranged at the lower end of the last-segment stuffing column. According to the utility model, the number and stuffing of the stuffing columns and the stuffing of the last-segment stuffing column can be flexibly changed according to actual requirements and the multi-stage separation of complicated mixtures can be realized; the stuffing columns play a role of separation; and the liquid storage bottles are convenient for the addition of eluent so that constant manual addition is not required. The multi-segment chromatographic column has the advantages of simple structure, convenience in use and good effect.
Description
Technical field
The utility model relates to chemical field, specifically a kind of multistage chromatographic column that is applicable to mixture separation.
Background technology
In chemical experiment; Column chromatography for separation is a separating mixture equipment commonly used, and existing chromatographic column is made up of the liquid storage bottle and the filled column of disjunctor, or independent filled column is formed; There is following problem: fill it up with eluant, eluent in (1) liquid storage bottle; Sample segment is dissolved by eluant, eluent, causes separating trailing, and can't reach more excellent separating effect; (2) filler is single fixing, can not change filler flexibly, targetedly, can not carry out multi-stage separation to the family's component in the mixture.
Summary of the invention
The purpose of the utility model is the weak point that overcomes in the prior art, and a kind of simple in structure, multistage chromatographic column that can effectively prevent to trail, can be used for flexibly the complex mixture multi-stage separation is provided.
The multistage chromatographic column of the utility model; Comprise main liquid storage bottle, a plurality of secondary liquid storage bottle that links to each other with main liquid storage bottle; The bottom of main liquid storage bottle and a plurality of secondary liquid storage bottles is equipped with choke valve, and between main liquid storage bottle and the secondary liquid storage bottle, be equipped with filled column between secondary liquid storage bottle and the secondary liquid storage bottle, the filled column below is equipped with T tube; Be equipped with triple valve on each T tube; Be equipped with the solvent inlet on each secondary liquid storage bottle, the below of the last secondary liquid storage bottle is provided with the latter end filled column, and the lower end of latter end filled column is provided with valve.
Be provided with between described filled column and the T tube and gather the tetrafluoro junction pipe.
Beneficial effect: owing to adopted technique scheme; The eluant, eluent discharge rate is identical with eluent outflow speed in filled column and the terminal filled column in control throttle valve control master liquid storage bottle and the secondary liquid storage bottle; The eluant, eluent that can realize the filler top in filled column and the terminal filled column remains lower liquid level; Greatly reduce the eluant, eluent volume that directly contacts with sample, can effectively prevent hangover.The multistage chromatographic column can be according to actual needs; Change the quantity of filled column and the filler of filler and terminal filled column flexibly, realize the multi-stage separation of complex mixture, filled column plays centrifugation; Liquid storage bottle can make things convenient for the interpolation of eluant, eluent, and eluant, eluent is added in manual work constantly.It is simple in structure, easy to use, effective.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: main liquid storage bottle-1, secondary liquid storage bottle-2, filled column-3 gathers tetrafluoro junction pipe-4, T tube-5, choke valve-6, solvent inlet-7, latter end filled column-8, valve-9, triple valve-10.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further description:
Shown in accompanying drawing 1, the multistage chromatographic column mainly by main liquid storage bottle 1, a plurality of secondary liquid storage bottle 2, filled column 3, gather tetrafluoro junction pipe 4, T tube 5 and latter end filled column 8 and constitute.Main liquid storage bottle 1 links to each other with a plurality of secondary liquid storage bottles 2; The bottom of main liquid storage bottle 1 and a plurality of secondary liquid storage bottles 2 is equipped with choke valve 6, and between main liquid storage bottle 1 and the secondary liquid storage bottle 2, be equipped with filled column 3 between secondary liquid storage bottle 2 and the secondary liquid storage bottle 2, filled column 3 belows are equipped with T tube 5; Be provided with between filled column 3 and the T tube 5 and gather tetrafluoro junction pipe 4; The end opening and the T tube 5 of tetrafluoro junction pipe 4 bonding pad posts 3 are suitable for reading, and the end opening of T tube 5 is a ground, are connected with the suitable for reading of secondary liquid storage bottle 2.Be equipped with triple valve 10 on each T tube 5, be equipped with solvent inlet 7 on each secondary liquid storage bottle 2, the below of the last secondary liquid storage bottle 2 is provided with latter end filled column 8, and the lower end of latter end filled column 8 is provided with valve 9.The end opening of main liquid storage bottle 1 and secondary liquid storage bottle 2, the ground that is suitable for reading of filled column 3 and latter end filled column 8, choke valve 6, valve 9 and triple valve 10 are and gather the tetrafluoro material.
Operation principle: through the eluant, eluent drop rate in main liquid storage bottle 1 of choke valve 6 controls and the secondary liquid storage bottle 2; Make the eluents outflow speed in main liquid storage bottle 1 and secondary liquid storage bottle 2 interior eluant, eluent discharge rates and filled column 3 and the terminal filled column 8 identical; The eluant, eluent of realizing the filler top in filled column 3 and the terminal filled column 8 remains lower liquid level, prevents hangover.Increase secondary liquid storage bottle 2 and form the multistage chromatographic column with filled column 3 and by following connected mode: secondary liquid storage bottle 2 end openings and filled column 3 are suitable for reading to join with ground, and secondary liquid storage bottle 2 is suitable for reading to be connected with T tube 5 through gathering tetrafluoro junction pipe 4 with filled column 3 end openings.Change the quantity of filled column and the filler of filler and terminal filled column according to actual needs, realize flexible multi-stage separation.
