Abstract:
The article describes implementation of absorption spectroscopy methods for construction of trace compounds sensors in air. Multipass spectroscopy with laser wavelength modulation as well as cavity ring down spectroscopy was applied. High detection limits and good selectivity sensors of nitrogen oxide, dioxide, carbonyl sulphide, ethane, ammonia, methane, carbon oxide, acetone and water vapour were elaborated. The sensors were used in experiments about security and environmental monitoring, human breath analysis as well as for the geophysical research.
