Abstract
The utility model relates to a combined type dry-pillar chromatographic pillar for the organic mixtures chromatographic separation and is composed of a plurality of pillar body segments which can be connected together or disconnected, a pillar bottom segment, a funnel segment and a filtering plate arranged at the bottom part of the pillar bottom segment. The combined type dry-pillar chromatographic pillar solves the disadvantages that the filling material in the existing chromatographic pillar is inconvenient to load and is inconvenient to take out after the chromatographic separation is completed; the existing chromatographic pillar can be only used once. The combined type dry-pillar chromatographic pillar can be widely used for the lab chromatographic separation of organic mixtures of various sciences, such as the biochemistry, the chemical industry, etc., in particular to the chromatographic separation of the chemical constitution portion and antibiotics in the Chinese herbal medicine.
Description
The utility model relates to a kind of device that is used for the organic mixture chromatography, is a kind of dry chromatography post specifically.
Dry chromatography is meant with inserts is dried dresses up the separation method that post carries out chromatography, be widely used in the laboratory chromatography of all multidisciplinary organic compounds such as biochemistry, chemical industry, especially aspects such as chemical composition in separating Chinese herbal medicine and antibiotic are used more popular.
At present, Chang Yong dry chromatography post is whole glass column and plastic sheeting post.The weak point of glass column is: after chromatography finishes, glass column segmentation cutting just can must be got the filler of different section layers, and operation inconvenience, and every glass column can only use once relatively waste; The weak point of plastic sheeting post is: the dress post is difficulty relatively, and because some organic solvent has certain corrosivity to it, thereby be subjected to certain restriction in the use.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of dress post convenient, reusable combined type dry chromatography post.
The purpose of this utility model can reach by following technical solution: a kind of dry chromatography post, its special character is, form by a plurality of cylinder joints that are linked together, a post coxopodite, a funnel joint and a filter plate that is positioned at post coxopodite bottom, between the described cylinder joint, between cylinder joint and the post coxopodite and the post coxopodite with all are removable connections between funnel saves.
Removable connection in the above-mentioned technical solution can be a thread connection.In order to prevent seepage, can between connector, add a sealing ring.
Cylinder joint length in the above-mentioned technical solution is advisable with 3～8cm, and with suitable, be advisable with 0.05～0.15cm by the filtering holes aperture on the filter plate with 1～10cm for diameter.
Cylinder joint in the utility model, post coxopodite and funnel joint are to be made by the organic compound or the metal material of acid and alkali resistance and organic solvent, as polytetrafluoroethylplastic plastic, and lucite, stainless steel, titanium alloy etc.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the axial sectional structure chart of combined type dry chromatography post;
Fig. 2 is the A-A cutaway view of Fig. 1.
In conjunction with the accompanying drawings embodiment to of the present utility model be described in detail as follows:
This combined type dry chromatography post has the cylinder joint 1 of a plurality of length between 3～8cm, between the cylinder joint is thread connection, a cylinder joint is bottom gone up and in the mode of thread connection a post coxopodite 2 is installed, a filter plate 3 is established in the bottom of post coxopodite, this filter plate is provided with the filtering holes of a plurality of apertures between 0.05～0.15cm, a funnel joint 4 is installed in the mode of thread connection in the lower end of post coxopodite 2, a step 5 is established in the bottom surface of this funnel joint, thereby the filter plate bottom surface can not pasted mutually with funnel joint bottom, being beneficial to liquid flows down, there is an outlet 6 in its central authorities, are the passages that liquid is discharged.
During use, can select the cylinder joint of differing heights as required, combine with thread connection, the minor details of post coxopodite with the cylinder joint are connected, the funnel joint connects with the lower end of post coxopodite, promptly is combined into complete dry chromatography post.In order to prevent to leak under the filler, can on filter plate, place a circular filter paper, in post, add inserts then, the preparation that can carry out dry chromatography separates, after the preparation separation is finished, with the cylinder joint of chromatographic column, post coxopodite and funnel joint are taken apart successively, extract each several part with apparatus,Soxhlet's, promptly obtain the organic compound that contains different components, different content of different levels, use for further assay.Clean various piece at last, in order to using again next time.
Can find out that in conjunction with above embodiment the utility model has following advantage compared to existing technology:
1, chromatographic column by a plurality of cylinders save, post coxopodite, a funnel joint combine, can dismantle, thus inserts pack into and the taking-up of chromatography after finishing all very convenient;
But 2, chromatographic column Reusability has reduced the waste of material.
Claims (4)
1, a kind of combined type dry chromatography post is characterized in that: is made up of the removable a plurality of cylinders joint that is linked together, a post coxopodite, a funnel joint successively, is provided with a filter plate bottom the described post coxopodite.
2, combined type dry chromatography post according to claim 1, it is characterized in that: described removable connection is a thread connection.
