Description

Technical field [0001] The invention relates to the field of laboratory automation equipment, in particular to a fully automatic adsorption experimental device. Background technique [0002] Laboratory adsorption materials are widely used in the purification and enrichment of samples. The adsorption can be divided into two main forms: physical adsorption and chemical adsorption. The physical adsorption process mainly attracts impurities in liquid or gaseous media to the pores of the adsorption material with porous structure and huge surface area to achieve the purpose of collecting impurities and enriching products. The chemical adsorption process means that the specific functional groups or complexes contained in the adsorbent material can chemically react with the adsorbed material, so that the adsorbed material binds to the surface of the adsorbent material, and achieves the experimental purpose of purification or enrichment. [0003] In many adsorption purification and enrichm...

Problems solved by technology

[0006] Although the resin adsorption device disclosed in the above-mentioned utility model patent can process dozens of samples at the same time, and can improve the sample processing efficiency to a certain extent, this utility model uses a glass liquid addition hopper to set the amount of feed liquid for the sample. After the feed liquid is used up, it needs to be added manually again, which requires manual cooperation, which increases the labor intensity of laboratory personnel, the degree of automation is low, and the space occupied by the device is relatively large; the above-mentioned invention patent discloses a macroporous resin adsorption separation device , to a certain extent, the adsorption separation of samples can be achieved, but it is limited to the adsorption separation of one sample, and this adsorption device occupies a large space, so it is not suitable for laboratory operation
