Problems solved by technology

The chromatographic column needs to use a large amount of eluent. When using a pressurized column, the cover needs to be opened to stop the operation every time the eluent is added, and the elution is carried out after adding the liquid. The size of will affect the separation efficiency by affecting the eluent flow rate

Abstract

The invention provides a chromatography device including a chromatography tank and an eluent storage tank; the chromatography tank is composed of a chromatography tank body, an upper sealing cover and a lower sealing cover; the lower sealing cover is provided with a liquid outlet; the upper sealing cover is provided with an air inlet and a liquid inlet; a liquid distributor is arranged between the upper sealing cover and the chromatography tank body; a sieve plate is arranged between the chromatography tank body and the lower sealing cover; a flow pump is arranged between the chromatography tank and the eluent storage tank; the chromatography tank body is provided with a liquid level sensor and a pressure sensor; the liquid level sensor and the flow pump are connected through a wire; the pressure sensor and a compression air pump are connected through a wire. The chromatography device realizes an operation of adding an eluent without stopping working under a pressurization condition, also can constantly monitor and control the height of the eluent, and prevents the eluent from being drained off in the chromatography tank. The device is simple and is easy to operate.

Description

technical field [0001] The invention belongs to the field of separation devices, in particular to a chromatographic separation device. Background technique [0002] In the production process of the chemical and pharmaceutical industries, it is often necessary to purify or separate intermediate products or products. As a common separation device, chromatography columns are widely used. The chromatographic column needs to use a large amount of eluent. When using a pressurized column, the cover needs to be opened to stop the operation every time the eluent is added, and the elution is carried out after adding the liquid. The size of will affect the separation efficiency by affecting the eluent flow rate. During the elution process, the eluent running dry will affect the separation, so it is necessary to monitor the liquid level of the eluent from time to time. Contents of the invention [0003] In view of this, the present invention aims to propose a chromatographic device,...
