Problems solved by technology

[0002] Chromatographic columns are widely used as common equipment for separation and purification. In the prior art, most of the chromatographic columns are straight cylindrical structures. , the part of the filler that is in contact with the inner surface of the column is always wetted before the middle filler, which causes the chromatographic band of the column to be distorted and widened, reducing the resolution

Embodiment

[0011] In this embodiment, a chromatographic column device, such as figure 1 As shown, it includes a column neck 1 with a standard frosted mouth, a column shoulder 2 and a column body 3. The diameter of the column neck 1 is 25% to 50% of the diameter of the column body 3. The column shoulder 2 is in the shape of an inverted funnel, narrow at the top and wide at the bottom. Connect column neck 1 and column 3. When packing the column, the filler is installed to the neck 1 of the column, and the sample to be separated is filled in the neck 1, and the mechanical principle can be used during elution to make the eluent drive the diffusion of the chromatographic band and make the color band uniform.

[0012] In this embodiment, the principle of mechanics is used to make the chromatographic filler wet evenly, the chromatographic band becomes narrower and more orderly, and the chromatographic separation degree is improved.

Abstract

The invention discloses a chromatographic column device. The chromatographic column device comprises a column neck with a frosted opening, a column shoulder and a column body. The diameter of the column neck is 25%-50% of the diameter of the column body. The column shoulder is inverted-funnel-shaped, the upper part is narrow and the lower part is wide. The column shoulder is connected with the column neck and the column body. By utilization of mechanics principles, chromatographic filling materials can be infiltrated uniformly, a chromatographic band is narrowed and tidy, and the chromatographic resolution is raised.

Description

technical field [0001] The invention relates to the field of chemical separation and purification, in particular to a chromatographic column device. Background technique [0002] Chromatographic columns are widely used as common equipment for separation and purification. In the prior art, most of the chromatographic columns are straight cylindrical structures. , the part of the filler that is in contact with the inner surface of the chromatography column is always wetted before the middle filler, which causes the chromatographic band of the chromatography column to be distorted and widened, and the resolution is reduced. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a chromatographic column device, so that the dry-packed packing can permeate evenly and improve the separation degree. [0004] The purpose of the present invention will be achieved through the following technical s...
