Laser-based trace gas sensing is attractive alternative to other detection techniques, such as mass spectrometry or gas chromatography. In this project we focus on optical-based detection of hydrogen sulfide.
Hydrogen sulfide is colorless, flammable, explosive and highly toxic. It naturally appears in the vicinity of active volcanos and thermal springs. However, large part of hydrogen sulfide emission has anthropogenic origin, for example from petroleum refineries (mainly due to hydrodesulfurization process, which is used to remove sulfur from petroleum). Other sources includes sewer systems, septic tanks or industrial animal farming. It can also be found in underground mines.
Within the frames of this project:

  • we will characterize spectral regions that enable hydrogen sulfide sensing;
  • a system for remote, stand-off detection of hydrogen sulfide will be built and demonstrated;
  • a system for point sensing of hydrogen sulfide using multi-pass cell will be developed;
  • a method for real-time calibration of this sensor will be proposed and demonstrated;
  • sensors will be tested outside laboratory.
