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...
