CONTINUOUS MEASUREMENT of SULFUR in GASES (Baie SO2) Measure by UV Fluorescence From 5 ppb to 10 ppm In alimentary CO2 PRINCIPLE Combustion under oxygen of sulphured compounds with formation of SO2 measured continuously by a specific UV fluorescent detector. We propose equivalent equipment for the measurement of nitrogen compounds. APPLICATIONS Mainly control of alimentary CO2, and also any other gas compatible with the method requirements.
