Diode laser-based gas analyser for the simultaneous measurement of CO<sub>2</sub> and HF in volcanic plumes
A portable analyser is described for simultaneous detection of CO<sub>2</sub> and HF emitted by volcanoes and fumaroles. The system is based on two fibre-coupled distributed feedback lasers and only one multipass cell, and provides the absolute concentration values of the two gases, w...
