Spectroscopic analysis equipment that utilizes fluorescence emission properties of substances to perform quantitative and qualitative analysis of molecular structure and concentration. Measures fluorescence generated by excitation light irradiation, used in manufacturing for raw material quality control, trace component analysis in products, and detection of additives and impurities. Supports wide applications including catalyst activity evaluation in chemical industry, additive analysis in food industry, and fluorescence property evaluation of electronic materials. Distinguished from UV-visible spectrophotometers by using fluorescence emission as measurement principle, and from Raman spectrometers by detecting emission light rather than scattered light.
