Problems solved by technology

[0004] At present, the time-resolved fluorescence immunoassay analyzer commercialized in my country can only perform a single detection (that is, only one target can be detected at a time), resulting in repeated detection, time-consuming, and waste of raw materials; while the time-resolved fluorescence immunoassay analyzer combined with fluorescence Immunochromatography card simultaneously detects two or more targets, which has not been reported so far
In addition, the currently disclosed time-resolved fluorescence immunoassay analyzer needs to reset the parameters for each measurement, the data analysis and processing ability is weak, and the degree of automation is low.

Description

technical field [0001] The invention relates to a time-resolved fluorescence immunoassay analyzer with multi-channel detection function and its application, belonging to the technical field of immune chromatography and the field of food safety detection. Background technique [0002] Time-resolved fluorescent immunoassay (TRFIA) is a rapid immunochromatographic detection technology emerging in recent years. Its principle is to use special fluorescent lanthanide ions combined with chelating agents as tracers. A reaction occurs in a certain antigen-antibody immune reaction system, and the specific fluorescence intensity in the product is measured with a time-resolved fluorescence immunoassay analyzer, so as to achieve the purpose of quantitative analysis of the analyte. Using the TRFIA method to detect trace substances has the characteristics of simple operation, convenience, and speed, and has the advantages of high sensitivity, stability, and high accuracy. Therefore, it has...
