Please join us for a discussion of the market for laser-based gas analyzers for use in environmental monitoring. This webinar will begin with a presentation that explores the range of laser-based gas analyzers applied to environmental market applications, using examples to demonstrate the value added by use of this technology. We will discuss established technologies and techniques, some of the limitations of near-infrared lasers for spectroscopy and the potential of mid-infrared lasers to further improve on the state of the art.

The investigation of the carbon cycle provides an excellent example of how laser-based gas analyzers have revolutionized the collection of accurate and reliable data, informing groups relying on near real time analysis to make important decisions in the short-term, while providing the short-term precision and long-term stability to monitor changes in our environment over a period of decades. Using product examples from several key players providing instrumentation to this area, we can see how scientists have progressed from observing long-term increases in atmospheric greenhouse gases, to locating and quantifying both natural and anthropological sources and sinks of these gases, effectively informing policy makers in their attempts to reduce emissions and limit increasing global temperature. Now increasingly being taken up by industry as emitters respond to the call for Net Zero following commitments made at the COP26 summit in 2021, laser-based gas analyzers will continue to play an increasingly important role in achieving this target.

Following Dr. Leggett’s presentation, the moderator will lead a discussion about the environmental sensing market and take questions from the attendees.

What You Will Learn:

  • the wide range of measurement applications served by laser-based gas analyzers
  • the advantages offered by laser-based instruments versus previous generation instruments
  • limitations of near-infrared lasers and desired improvement in mid-infrared technology

Who Should Attend:

  • laser manufacturers and research groups
  • environmental service providers
  • companies looking to meet Net Zero targets
