Description
Technical Field
The utility model relates to a chromatographic column technical field specifically is a novel chromatographic column structure.
Background
The separation of chromatography is that each component dissolved in mobile phase passes through chromatographic column (stationary phase), because each component has different action with stationary phase, and the retention time in stationary phase is different, so it flows out from stationary phase successively, so that it can be separated. The high performance liquid chromatography system has high requirements on the temperature of a chromatographic column, and a chromatographic column thermostat (column incubator) can accurately and stably control the service temperature of the chromatographic column, has non-negligible effects on improving the column efficiency of the chromatographic column, improving the resolution of a chromatographic peak, shortening the retention time, reducing the back pressure, ensuring the repeatability of an analysis sample result and the like, and the chromatographic column needs to be frequently replaced according to different separation objects; for example, patent No. CN2016105047272 discloses "a column oven capable of rapidly replacing a chromatography column", and proposes a novel chromatography column structure in order to match it with rapid replacement of the chromatography column.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel chromatographic column structure to it is difficult to solve among the prior art chromatographic column and change taking trouble, still needs the problem of certain skill.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel chromatographic column structure, strains cap and two sieves including body, column casing end cap, two, the one end threaded connection of body has the column casing end cap, be equipped with the sieve in the circular slot that the inboard of straining the cap was seted up, one strain the inner chamber right side of cap interference fit body of impressing, and its inner wall contact that is equipped with the side of sieve and body, another strain the inner chamber left side of cap interference fit compression column casing end cap, and its outer wall contact that is equipped with the side of sieve and body.
Preferably, the cross section of body is the type of protruding, and the body is hollow.
Preferably, the outer side surface of the filter cap is arc-shaped.
Preferably, the inner cavity of the filter cap is provided with through holes along the left-right direction.
Preferably, the diameter of the through hole is smaller than that of the circular groove, the diameter of the circular groove is smaller than that of the left side of the inner cavity of the tube body, and the diameter of the left side of the inner cavity of the tube body is smaller than that of the right side of the inner cavity of the tube body.
The utility model has the advantages that: the problem of labor and time consumption in replacement can be well solved, and the replacement of the chromatographic column can be safely and quickly completed even by inexperienced operators.
