AI Technical Summary

Problems solved by technology

The exhaust groove of this structure is placed in the middle of the column, and the effective height of the column is reduced. When the column bed of the same height is filled, the overall height of the chromatographic column is much higher, which virtually increases the production cost and is not easy to operate.

Embodiment Construction

[0015] The present invention will be further described in detail with reference to Fig. 3 to Fig. 8 .

[0016] The first embodiment of the present invention is shown in Figures 3 to 5, consisting of a piston support assembly 1, a piston 2, a column upper flange 3, a column 4, a column lower flange 5, an end cover assembly 6, and an exhaust pipe 7. Seal ring A 8, seal ring B 9 and exhaust groove 10 are formed. Piston 2 is provided with two exhaust holes 11, and exhaust hole 11 is connected with exhaust pipe 7.

[0017] When the chromatographic column is exhausted, move the piston 2 to the exhaust position (as shown in Figure 3), the sealing ring A 8 is fitted and sealed with the upper flange 3 of the column cylinder, and the sealing ring B 9 is in the position of the exhaust groove (10). An unsealed state is formed, and the exhaust hole 11 on the piston 2 and the exhaust pipe 7 communicate with the outside world. The granular medium is pumped into the cylinder 4 from the end c...

Abstract

The invention provides a novel chromatographic column capable of exhausting air, which is composed of a piston supporting assembly, a piston, column casing upper flanges, column casings, column casing lower flanges, an end cap assembly, exhaust pipes, seal rings A, seal rings B and air exhausting slots; two air-exhausting holes are formed in the piston or the column casing upper flanges, and are connected with the exhaust pipes. According to the chromatographic column provided by the invention, air in the column casings can be conveniently exhausted by an air-exhausting structure of the chromatographic column; the effective height of the column casings is increased and the total height of the chromatographic column is reduced; furthermore, the situation that liquid overflows to pollute the piston is avoided.

Description

technical field [0001] The invention relates to a novel chromatographic column that can be exhausted, and belongs to the field of preparation chromatography. Background technique [0002] The preparative chromatographic column is an important technical means to separate the required target substance from the complex liquid system. During the separation, the mobile phase carrying the sample is driven by pressure to move through the granular medium of the stationary phase in the column bed. According to the movement through the medium The time for the sample to flow out of the chromatographic column is different depending on the rate, thereby realizing the separation of the sample. The bed of granular media is formed under gravity, by flushing with the mobile phase, or by piston compression of the chromatography column, but trapped air in the bed creates air pockets between the sample and the stationary phase of the granular media, Thus directly affecting the separation effec...
