The analyzer is generally composed of a host and a computer. The host is the operational response measurement part of the instrument, which is mainly composed of a material preparation module, a liquid path module, a mechanical transmission module, an optical path detection module, and a circuit control module. The material preparation module includes a reaction cup, a sample tray, a reagent tray, a storage and processing device for cleaning liquid and waste liquid on the instrument. The liquid path module includes filters, sealing rings, vacuum pumps, pipes, sample probes and reagent probes. The mechanical transmission module includes sensors, transportation rails, and robotic arms. The optical path detection module includes a photomultiplier tube; the circuit control module includes a power supply and a circuit control board. The computer is the core part and control center of the instrument, which mainly includes computer and random software, which is mainly used for program-controlled operation of the instrument, data processing of test results, and instruction judgment. The applicant should describe in detail the name of each component module, the manufacturer, and the specific components of each module based on the specific characteristics of the declared product, and describe in detail the main function of the declared product and the function of each component module. It can be combined with text descriptions and photos. The form is clearly stated.
