Problems solved by technology

Due to the insufficient sensitivity of the current commercial instruments, the specificity of the determination is not strong, and the sensitivity and selectivity of the instrument need to be further improved in order to directly analyze water samples and obtain the most reliable data.
[0005] But so far, there are no industrialized, low-cost, and easy-to-use fully automatic chemiluminescent immunoassay devices at home and abroad.

Description

technical field [0001] The invention relates to an electromechanical device, in particular to a fully automatic chemiluminescence immunoassay device. Background technique [0002] Chemiluminescence immunoassay (CLIA) technology is an ultra-trace active substance detection technology, which is widely used and is the most promising immunoassay method at present. It has the unique advantages of realizing homogeneous measurement and multiple detection. At the same time, the chemiluminescence instrument has been developed into full automation, and all work is controlled by the computer: from sample addition, transmission, incubation, separation, washing and measurement to data processing and result printing. [0003] my country's chemiluminescence research started in the 1980s, and there have been dozens of models of domestic chemiluminescence analyzers, but most of them are only at the laboratory level. The practically applied instruments are currently simple in structure, easy...
