Abstract

The first field measurements of volcanic gases using mid-IR difference frequency laser spectroscopy are reported. The results were obtained at the summit crater of Masaya volcano, Nicaragua, with the gases being drawn into a multi-pass cell and measured at reduced pressure. Automated sensitive and selective detection Of CO2 SO2, (HCl)-Cl-35,37, H2O, and CH4 was achieved. Simultaneous measurements obtained with open-path Fourier transform spectroscopy provide a useful comparison of the two optical techniques. We also consider the potential measurement of CO2 isotopic ratios in volcanic gases using laser-based spectroscopy. (C) 2002 Elsevier Science Ltd. All rights reserved.
