Development of a Midinfrared Cavity Ring-Down Spectrometer for High-Precision Analysis of Carbon Dioxide Clumped Isotopic Compositions
{{output}}
A midinfrared cavity ring-down (CRD) spectrometer was developed employing a 4.44 μm quantum cascade laser (QCL) for the sensitive detection of CO2 isotopologues, including 12C16O2 (44), 13C16O2 (45), 12C16O18O (46), and 13C16O18O (47). Instead of using an aco... ...
