Abstract
The invention relates to the technical field of analytical chemistry, specifically to a liquid chromatographic column for high-efficiency separation. The liquid chromatographic column comprises a column tube, pressure caps connected with two ends of the column tube through screw threads, sealing rings inlaid between the column tube and the pressure caps, a filling material in the inner cavity of the column tube and non-woven fabric filter discs placed between the bottoms of the sealing rings and the filling material, wherein the inner wall of the column tube is of a uniformly distributed concavo-convex cambered-surface structure and the surface of the inner wall is coated with an anticorrosion coating. Compared with the prior art, the column bottom collector provided by the invention has a simple structure, is convenient and practical and is suitable for popularization and application.
Description
Technical field
The present invention relates to technical field of analytical chemistry, be specially a kind of efficient separation liquid-phase chromatographic column.
Background technology
Chromatography is when utilizing mobile phase and Stationary liquid to make relativity, the distribution of material in two-phase from completely different from only having minute differences, thus compounding substances is carried out quantitative test a kind of analysis means.Chromatographic column is the critical component of the instrument realizing said method, traditional chromatographic column is made up of column joint, filtration unit, packoff and column jecket, the technique of combining closely of each ingredient is comparatively complicated, sealing effectiveness is better, but inboard wall of cylinder is all generally straight-tube shape, filler is generally granular, the space existed between filler and inboard wall of cylinder easily makes blend sample when directly arriving outlet without when filler, and this has brought great impact by giving the test result of later stage spectrogram display.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of structure simple, convenient and practical efficient separation liquid-phase chromatographic column.
The technical solution adopted for the present invention to solve the technical problems is: a kind of efficient separation liquid-phase chromatographic column, this chromatographic column comprises column jecket, be threaded connection pressure cap at column jecket two ends, be entrenched in sealing ring between column jecket top and pressure cap, be filled in the filler of column jecket inner chamber, be positioned over nonwoven fabrics filter disc bottom sealing ring and between filler, described column jecket inwall is equally distributed concavo-convex globoidal structure, and inner wall surface is coated with corrosion-resistant coating.
Further, the outside surface at described column jecket two ends has screw thread.
Beneficial effect: compared with prior art, structure of the present invention is comparatively simple, and column jecket inwall is the setting of concavo-convex globoidal structure, can effectively prevent biased sample from directly entering outlet by the space of column jecket and filler, thus the error effectively avoiding the later stage to test, convenient and practical, be suitable for applying.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described;
Fig. 1 is structural representation of the present invention;
In figure, 1. column jecket, 3. pressure cap, 4. sealing ring, 7. filter disc, 8. filler.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described;
One as shown in drawings is efficiently separated with liquid-phase chromatographic column, this chromatographic column comprises column jecket 1, be threaded connection pressure cap 3 at column jecket two ends, be entrenched in sealing ring 4 between column jecket 1 top and pressure cap 3, be filled in the filler 8 of column jecket inner chamber, be positioned over nonwoven fabrics filter disc 7 bottom sealing ring 4 and between filler 8, described column jecket 1 inwall is equally distributed concavo-convex globoidal structure, inner wall surface is coated with corrosion-resistant coating, the outside surface at column jecket 1 two ends has screw thread, and the inner surface of pressure cap 3 has the internal thread of coupling mutually.
The lower end of liquid-phase chromatographic column of the present invention is injection port, and upper end is outlet, and upper end outlet and lower end injection port are symmetrically arranged identical structure, and the caliber at the center of upper end outlet from bottom to top diminishes gradually.Biased sample first by lower end injection port make sample first in the middle part of sealing ring 4 by the nonwoven fabrics filter disc 7 of lower end, be then separated by filler, then pass from the nonwoven fabrics filter disc 7 of upper end, from upper end outlet to lower step pick-up unit.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to right.
Claims (2)
1. an efficient separation liquid-phase chromatographic column, it is characterized in that: this chromatographic column comprises column jecket, be threaded connection pressure cap at column jecket two ends, be entrenched in sealing ring between column jecket top and pressure cap, be filled in the filler of column jecket inner chamber, be positioned over nonwoven fabrics filter disc bottom sealing ring and between filler, described column jecket inwall is equally distributed concavo-convex globoidal structure, and inner wall surface is coated with corrosion-resistant coating.
2. efficient separation liquid-phase chromatographic column according to claim 1, is characterized in that: the outside surface at described column jecket two ends has screw thread.
