Project details: Quantum cascade laser spectroscopy for N2O trace gas analysis

 

 

 

Industries
  • Gas Analysis, Medical Technology

 

Technology fields
  • Bus Systems and Radio, CAE, Software Development, Gas Analysis, Optical Measuring Systems; Measurement, Control and Regulation Technology

 

Project requirements
  • The aim of the project was the development of a compact, well-integrable analyzer module consisting of a long way cell (Herriott) and an electronic control for trace gas analysis of N2O. Beside N2O, the gases CO, CO2 and O3 shall be determinable. A fast response time (T90: 1-2 seconds), no cross-sensitivities to other gases, and a low detection limit of <10 ppbV are the characteristic conditions that were set on this project.

 

Facts / Highlights
  • No LN2 necessary, detector is cooling with ambient air
  • Simple calibration, even without N2O-span gases, possible
  • Completely fulfills EURO VI requirements
  • Compatible through compact construction
  • High selectivity and sensitivity
  • No cross-sensitivities
  • Adjustment for various gases is possible
  • Electronics with a variety of lasers operable (QCL, DFB, ICL, ...)

 

Services of KNESTEL
  • Potential analysis, target price estimate, project management; development of software, hardware and optics; support with the mechanical construction, EMC testing, serial production

 

Possible applications
  • Gas analysis in research, development and quality assurance
  • Environmental technology
  • Process monitoring
  • Medical technology, breath gas analysis
