Pollutant Gases

Infrared technology for remote detection of pollutant gases, whatever the source

Growing environmental concern, more restrictive legislation, harmful effects to health and the environment due to uncontrolled emissions of SO2, CO, CO2, HCs… all of them are factors that drives the development of technologies for pollutant emissions monitoring.

LIR-InfraRed LAB develops instruments based on multi and hyperspectral sensors, infrared cameras, imaging spectroradiometer and FTIR for gas analysis and detection.

Every polar gas molecules emit and absorb in a different infrared frequency; two gases never share the infrared spectrum if they do not have the same composition. Also, the emission and absorption spectrum provides additional information like temperature and concentration, needed data to evaluate real danger of the emission.

Optical imaging allows gas detection in a harmlessly and controlled manner. IR systems are able to cover large areas; the perfect tool for gas monitoring in any given environment. It is possible to setup alarms based on gas temperature, concentration or any parameters.

Know-how of this application is based on a deep knowledge of the scientific and technological basis involved. Each specific situation requires an ad-hoc study and design to develop the most suitable sensor.
