Abstract
Coal mine safety,petrochemicals,storage and transportation,atmospheric environment monitoring,combustion diagnosis,industrial process monitoring and control,and other industries all require high sensitivity real-time online multi-component gas detection solutions.In terms of optical technology,tunable diode laser absorption spectroscopy sensors have the characteristics of high sensitivity,good selectivity,fast response speed,and strong anti-interference ability.They have been proven to be an advanced technology for detecting multi-component gases.In the detection of multi-component gases,the presence of cross interference,cost,and performance requirements that cannot be ignored have become the main considerations in many detection scheme designs.The single laser for multi-component gas detection is introduced in detail,aiming to provide ready-made guidance for multi-component detection in various applications.
