Short summary
Assessing emissions of volcanos has a three-fold importance: providing input for climate evolution models (CO2 is one of the major constituents of emissions), quantifying pollutant emissions (HCl, HF and SO2 are released in hundreds of tons/day) and monitoring the status of the magmatic chambers. For these purposes we realized gas analysers based on spectroscopic techniques, which must be sensitive, light and resistant to the emitted gases. This paper reports on the measurement of CO2 and HF.
