Problems solved by technology

[0002] At present, the commonly used column frame structure for liquid chromatography instruments on the market is: the liquid inlet pipe joint is fixed on the slider, the liquid outlet pipe joint is fixed on the base structure, and the slider is vertically installed on the guide rail structure. The push-pull slider fixes the chromatographic column. The existing structure is not highly automated, the operation is cumbersome, and the position accuracy is difficult to grasp. In particular, it is easy to damage the Luer connector part of the chromatographic column, or the seal is not firm, resulting in frequent leakage.

Abstract

The invention discloses a convenient-to-control chromatographic column frame, which comprises a base, a guide rail slide block pair, a power transmission device and a control panel, wherein a first pipeline joint assembly is arranged on the base, and is used for connecting a lower interface of a chromatographic column in a sealed way; the guide rail slide block pair comprises a slide block and a guide rail; the slide block is glidingly matched on the guide rail; the power transmission device is in transmission connection with the slide block, so that the power transmission device drives the slide block to slide on the guide rail; a second pipeline joint assembly is arranged on the slide block; the second pipeline joint assembly is used for connecting an upper interface of the chromatographic column in a sealed way; the control panel is in signal control connection with the power transmission device, so that the control panel controls the power transmission device to act. The convenient-to-control chromatographic column frame has the advantages that the use is convenient and fast, the automation degree is high, the joint part of the chromatographic column cannot be damaged, and the accurate degree of the butt joint position is improved; the flowing phase seepage cannot be generated at higher work pressure; the sealing performance is good.

Description

technical field [0001] The invention relates to an easy-to-control chromatographic column frame, which belongs to the technical field of liquid chromatography. Background technique [0002] At present, the commonly used column frame structure for liquid chromatography instruments on the market is: the liquid inlet pipe joint is fixed on the slider, the liquid outlet pipe joint is fixed on the base structure, and the slider is vertically installed on the guide rail structure. The push-pull slider fixes the chromatographic column. The existing structure is not highly automated, the operation is cumbersome, and the position accuracy is difficult to grasp. In particular, it is easy to damage the Luer connector part of the chromatographic column, or the seal is not firm, resulting in frequent leakage. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a chromatographic column rac...
