Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to a multifunctional high-throughput automatic chromatography detector and its application. Background technique [0002] Chromatography is the abbreviation of "chromatographic analysis". It is a method of separating and measuring a multi-component mixture by using different properties of each component, using different separation media such as silica gel and detection instruments. Taking the commonly used immunochromatography as an example, the principle is to immobilize the specific antibody on a specific zone of the nitrocellulose membrane, and then add the sample dropwise to one end of the membrane. Under the action of the capillary, the sample is immediately Moving forward along the membrane, when moving to the area where the antibody is immobilized, the corresponding antigen in the sample will specifically bind to the antibody. At this time, if immunological n...
