In the field of industrial process gas analysis, traditional technologies face a series of challenges, including complex analysis processes, high consumable requirements, slow response times, limited analysis scope, and expensive maintenance costs. Sifang Instrument uses laser Raman technology to develop gas analysis instruments, and its innovative series of products have brought revolutionary progress to this field. The product enhances, collects, processes, and identifies specific Raman scattering spectra of the tested gas, and has participated in multiple major industry projects, enabling rapid and real-time online analysis of nearly 20 gas concentrations and calorific values simultaneously.
