20160615_123907 (1)Cavity Ring-Down Spectroscopy (CRDS) measures concentration of gas-phase molecules such as CO2, H2O, H2S, and NH3. CRDS is laser-based, enabling highly sensitive detection of CO2 and its isotopologues in a gas or solid. Our CRDS is used in combination with a combustion module to measure d13C in rocks. This provides a great alternative for mass spectrometry.
