Group for Laser Spectroscopy
We close the gap between research grade and field deployable laser based instrumentation by combining high-performance with compactness, robustness, autonomy and modularity. This results in mobile sensors capable for in situ and continuous analysis of single or multiple molecular species under field conditions. High-precision gas measurements are the key to answer specific research questions and advance our knowledge in many important areas related to climate, environment, agriculture and medical diagnostics.
Our research projects include the measurement of trace gas fluxes for CO2, N2O, CH4 and NO2, the determination of isotope ratios of CO2, N2O and CH4 in ambient air, and breath air analysis for clinical research.
- The in-situ and continuous measurement of CO2 stable isotopes at the high altitude research station Jungfraujoch (3580 m elevation, Switzerland), to characterize local and regional emission sources.
- Development and assessment of a high precision (~ppt level) instrumentation for direct and simultaneous NO and NO2 measurements under field conditions.
- High precision (< 0.1 ‰) analysis of N2O isotopomers.
- Flux measurements of relevant greenhouse gases
- IRSENS - the development of a gas sensing platform for environmental and industrial applications
- Very fast propellant gas detection for industrial leak surveillance
