Rapid Scanning Cavity Ring-down Spectrometer for the Precision Measurement of 13C/12C for CO2 in Air

Not Accessible

Your library or personal account may give you access

Abstract

We report a dual-wavelength rapid-scanning spectrometer with ≤1‰ measurement reproducibility for 13C/12C isotope ratios in air. Initial evaluations of accuracy were performed using gas samples with known δ13C.
