The laser Raman spectroscopy gas analyzer utilizes the Raman scattering effect and overcomes technical challenges such as weak characteristic signals, fluctuations in laser power and temperature to achieve gas analysis. The laser Raman spectroscopy gas analyzer can perform precise quantitative analysis of nearly 20 gas components including H2, N2, O2, CO, CO2, and CH4. [1]
The tunable semiconductor laser absorption spectroscopy technology is a technique that measures gas concentration by utilizing the wavelength tuning characteristic of semiconductor lasers and the selective absorption of the target gas by the laser. This technology has advantages such as high selectivity, fast response, no influence by moisture, and no drift. [1]
The non-dispersive infrared gas analyzer is based on the selective absorption of gases by infrared rays and can accurately identify and measure the concentration of target gases in complex production environments, effectively eliminating interference from other gases. [1]
The portable gas chromatograph inherits the core separation principle of traditional gas chromatography and achieves separation and detection by different components having different retention times in the chromatographic column. The portable GC realizes on-site rapid analysis through technologies such as micro-electromechanical systems (MEMS) and low-power design. [2]
Electrochemical sensors and catalytic combustion sensors are applied in gas detection.
