Isotope Analyzer for Real-Time Measurements in the Field
This project will employ Off-Axis Integrated Cavity Output Spectroscopy (Off-Axis ICOS) technology to develop, deploy, and test a field-portable methane isotope analyzer for the measurement of carbon isotope ratios (d13C) and methane (CH4) concentrations in ambient air. The instrument will be capable of providing in situ, accurate quantification of both CH4 concentration and carbon isotope ratio for the real-time monitoring of methane sources and sinks in the biosphere and atmosphere (e.g., in landfills, geological formations). The instrument will distinguish between biogenic and injected carbon sources, and will identify and subsequently capture fugitive methane emissions. Phase I will build, test, and deploy a prototype instrument capable of real-time measurements of methane isotopomers in ambient air. The prototype will employ a high-finesse optical cavity as a measurement cell. Commercial Applications and other Benefits as described by the awardee: Present technology is expensive and slow, and cannot provide on-site measurements of methane isotopomers in ambient air. A robust methane isotope analyzer should find uses in landfills, oil and gas exploration, and environmental research.
