Abstract
Description
Technical Field

[0002] At present, the fluorescence immunoassay analyzer is an instrument that can measure and analyze trace substances. It can convert the structure and characteristics of substances into measurable spectral signals. It has the characteristics of high detection sensitivity, strong specificity, rapidity, accuracy, and easy operation, and is not affected by the properties of the substance itself. The fluorescence immunoassay analyzer is a method of analyzing and detecting substances by using the specific fluorescence characteristics of substances. When a substance is exposed to a light source of a certain energy, the substance will emit fluorescence. This fluorescence is called excitation fluorescence. The wavelength of fluorescence is generally higher than the wavelength energy of the excitation light. Similarly, the fluorescence immunoassay analyzer also uses the principle of excitation fluorescence to achieve the detection of substances. It includes multiple parts such as excitation source, detection system, amplification system and display system. The fluorescence immunoassay analyzer has an excitation source to provide a light source of a specific wavelength. The light source excites the substance into a visible spectral signal, and then the detection system converts the spectral signal into an electrical signal so that it can be better detected. The amplification system can amplify the detected electrical signal to make the detection result more obvious. Finally, the display system converts the amplified signal into an image or data and displays it, so as to achieve the measurement and analysis of the substance.
