Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chromatography column equipment more particularly to a kind of oscillation equipment for chromatography column. BACKGROUND

[0002] Chromatography is a method for separating and determining multi-component mixtures by using the different physicochemical properties of each component.Chromatography is a technique that uses the different partition ratios of substances between the stationary phase and the mobile phase to achieve separation.Chromatography has very high resolving power for the separation and analysis of complex organic mixtures of biological macromolecules such as proteins and nucleic acids.Chromatography column is the main body in gel chromatography technology, usually made of glass tube or organic glass tube.Using the different adsorption capacities of each component in the mixture on the stationary phase and the different desorption capacities of the mobile phase, the mixture is allowed to flow through the stationary phase with the mobile phase, and the adsorption and desorption processes are repeated multiple times, so that the mixture is separated into two or more single pure components, which has the advantages of good separation effect and simple operation.With the increasing demand, some substances need to be frequently oscillated during separation operation in chromatography column, and there are few oscillation devices for chromatography column on the market, and most of them have simple structure, poor oscillation effect and usually can only oscillate one chromatography column at a time, which is low in efficiency, and the clamping operation is too cumbersome, which affects the separation efficiency.For this purpose, the present inventor proposes an oscillation device for chromatography column to solve this problem, which can clamp and oscillate multiple chromatography columns at the same time by setting multiple clamping devices on the oscillation device, improve the oscillation efficiency, and the clamping device is convenient and stable to effectively prevent falling.

Since the laboratory often needs to simultaneously oscillate multiple groups of chromatography columns in order to improve efficiency, otherwise, the low oscillation efficiency will affect the experiment or manufacturing process. Since the chromatography column is usually made of glass and has a cover on the top, the chromatography column needs to be effectively fastened and cannot fall off, including the cover. Therefore, it is better to fasten it with double insurance. Therefore, the structure of the chromatography column oscillation equipment needs to be improved to better clamp and fix the chromatography column and conveniently load and unload, and multiple groups of oscillation can be simultaneously performed, thereby further improving the practicability of the chromatography column oscillation equipment.
