Abstract
The invention relates to a liquid chromatographic column for analysis. The liquid chromatographic column comprises a column tube, an inlet pressure cap and an outlet pressure cap respectively connected with two ends of the column tube through screw threads, sealing rings respectively inlaid between the column tube and the inlet pressure cap and between the column tube and the outlet pressure cap, and a filling material in the inner cavity of the column tube, wherein the center of the inlet pressure cap is provided with a gas inlet, the center of the outlet pressure cap is provided with a gas outlet, the interiors of the gas inlet and the gas outlet are both provided with a sealing ball, a gas delivering pipe is fixedly connected with the center of the sealing ball, and the inner wall of the column tube is a uniformly-distributed accidented hemispherical surface. Compared with the prior art, the liquid chromatographic column for analysis has a simple structure; since the inner wall of the column tube is the uniformly-distributed accidented hemispherical surface, a mobile phase has difficulty in passing the great-particle size filling material; so the liquid chromatographic column for analysis is convenient and practical and is suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of analysis liquid-phase chromatographic column.
Background technology
Liquid phase chromatography is a kind of analytical approach being separated polycomponent sample, its principle utilizes each component of potpourri in two-phase, have different partition factors, when two-phase does relative motion, these materials carry out repetitious distribution to reach the object of separation in two-phase.Liquid-phase chromatographic column is the important factor in order of above-mentioned analysis result quality.Conventional liquid-phase chromatographic column is fine grain filler, but the fluid resistance of fine grain filler is often very large, and high-pressure pump must be adopted to be forced to be transported through pillar by mobile phase, and this type of pillar itself also must have good pressure-resistant seal performance; Adopt the fluid resistance of coarse grain footpath filler often less, but be easy to mobile phase is just discharged without filler.Therefore, the problem that a kind of analysis liquid-phase chromatographic column being applicable to coarse grain footpath filler is current research is developed.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of structure simple, convenient and practical analysis liquid-phase chromatographic column.
The technical solution adopted for the present invention to solve the technical problems is: a kind of analysis liquid-phase chromatographic column, this chromatographic column is comprised column jecket, is connected to the import pressure cap at column jecket two ends by screw thread and exports pressure cap, be entrenched in column jecket and import pressure cap, sealing ring between outlet pressure cap, be filled in the filler of column jecket inner chamber, described column jecket port has external thread, and the inwall of import pressure cap and outlet pressure cap all has the internal thread matched with column jecket port external thread; The center of import pressure cap is provided with air intake opening, and the center of outlet pressure cap is provided with gas outlet, and air intake opening and inside, gas outlet are provided with ball sealer, and ball sealer center has the gas piping be fixedly connected with; Described column jecket inwall is equally distributed concave-convex type hemisphere face; Be filled with absorbent wool between described filler and import pressure cap, between filler and outlet pressure cap, be filled with filter cotton.
Further, described ball sealer outside surface, air intake opening inwall and gas outlet inwall are coated with corrosion-resistant coating.
Beneficial effect: compared with prior art, the structure of analysis liquid-phase chromatographic column of the present invention is comparatively simple, and column jecket inwall is the hemispherical setting of equally distributed concave-convex type, can make mobile phase when through coarse grain footpath filler, not easily easily pass through, 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, 2. import pressure cap, 3. export pressure cap, 4. sealing ring, 5. filler, 6. absorbent wool, 7. filter cotton.
