Multi-channel fiber optic methane gas detector machine
features and advantage : The multi-channel fiber optic gas detector combines the advantages of fiber optic and TDLAS technologies, which are specifically reflected as follows:
Excellent gas selectivity, the detection process is not easily interfered by other gases;
All-optical detection means can be used safely in explosive environments;
The optimized design of the miniaturized fiber optic gas probe has a compact structure and high coupling efficiency; it is connected to the host through an all-fiber fiber, which has excellent long-term stability;
Using a near-infrared narrow-band tunable light source, one host can simultaneously detect methane gas concentrations at multiple measurement points, significantly reducing costs;
Fast detection speed, high sensitivity and long service life;
The optical fiber used is ordinary single-mode optical fiber, which is compatible with existing optical fiber communication networks to build detection systems. apply forSuitable for various point and quasi-distributed monitoring fields of methane gas:
Natural gas pipeline network leakage monitoring
Online intelligent monitoring of oil and gas pipelines
Coal mine safety production
Natural gas leakage detection in urban underground pipeline corridors
optical Fiber Raman Spectrometer
As an important spectral detection method, Raman spectroscopy has molecular fingerprint characteristics and is often used for the detection and identification of different substances. This product combines the surface-enhanced Raman scattering (SERS) effect with optical fiber sensing characteristics, and uses various types of optical fiber SERS probes developed to greatly improve the sensitivity of Raman spectrum detection and broaden the application range of portable Raman spectrometers. Combined with the optical fiber surface-enhanced Raman probe, the detection sensitivity of the portable Raman spectrometer is greatly improved;
⚫ Equipped with various specifications of Raman SERS probes to meet the needs of different application environments;
⚫ The fiber Raman probe with low-loss SMA interface can realize multiple insertion and removal of the fiber probe and Raman probe, which is convenient
Actual field application;
⚫ TE cooling CCD provides excellent performance such as low noise, high stability, and fast response. Combining the waveguide effect of optical fiber with the surface-enhanced Raman scattering (SERS) effect, we developed laser-induced evaporation self-assembly method, laser-induced liquid surface self-assembly method, slip-assisted self-assembly and other preparation methods with independent intellectual property rights, and developed Practical fiber optic SERS probes of various specifications. Relevant research work has been supported by many important scientific research projects such as the National 973 Program, the National Natural Science Foundation, and the Guangdong Provincial Natural Science Foundation. He has published more than 30 high-level SCI academic papers, authorized 3 U.S. invention patents, and authorized more than 11 Chinese invention patents. apply:Combining the optical fiber SERS probe with the developed portable Raman spectrometer has important application prospects in the field of liquid phase in-situ detection in food safety, environmental monitoring, biomedicine and other fields.
