Separated anti-scour glass chromatographic column

Abstract

The invention discloses a separated anti-scour glass chromatographic column. The separated anti-scour glass chromatographic column comprises a column body (1) and is characterized in that the column body (1) comprises a bottom column (2) used for accommodating a packing and a top column (3) used for accommodating an elution solution, wherein the bottom column (2) and the top column (3) are separated, frosted layers (4) used for being sealed and connected with the bottom column (2) and the top column (3) are arranged on the inner side wall of the bottom column (2) and the outer side wall of the top column (3) respectively, and a permeable ventilated first baffle (5) is arranged at the bottom end of the top column (3). The separated anti-scour glass chromatographic column provided by the invention is simple in structure and reasonable in design, the upper surface of the packing is prevented from being washed up, the used packing is taken out easily, and the separated anti-scour glass chromatographic column is suitable for being widely popularized and applied in a laboratory.

Description

technical field [0001] The invention relates to a separated anti-shock glass chromatographic column, which belongs to the technical field of chemical experiment consumables. Background technique [0002] The current glass chromatographic columns are all integrated, that is, an integral glass column with inlets and outlets on the top and bottom. The column packing method of this kind of glass column is divided into dry method and wet method, and the column packing is silica gel, resin or polymer. Amide, etc., regardless of dry method or wet method, the upper surface of the filler must be flat, and the current glass column can guarantee a smooth upper surface after installation, but it is easy to wash the upper surface of the filler when adding the elution solvent from the inlet. , even if cotton is placed on the upper surface of the filler, it is difficult to avoid this problem, that is, the current glass chromatographic column has no anti-shock function; in addition, the one...

Problems solved by technology

[0002] The current glass chromatographic columns are all integrated, that is, an integral glass column with inlets and outlets up and down. The column packing methods of this glass column are divided into dry method and wet method, and the column packing is silica gel, resin or polymer. Amide, etc., regardless of dry method or wet method, the upper surface of the filler must be flat, and the current glass column can guarantee a smooth upper surface after installation, but it is easy to wash the upper surface of the filler when adding the elution solvent from the inlet. , even if cotton is placed on the upper surface of the filler, it is difficult to avoid this problem, that is, the current glass chromatographic column has no anti-shock function; in addition, the one-piece glass chromatographic column has a small inlet, and the used filler is not easy to pour out from the inlet. Therefore, the existing glass chromatographic column has the problem that it is not easy to remove the used filler
