Nitrous oxide isotope ratio determination by mid-infrared laser spectroscopy

A fiber-coupled difference frequency generation laser spectrometer for measuring isotopic compositions of N 2 O at trace concentrations is presented. Using wavelength modulation 9 0 / 00 precision at 100 ppm is achieved. The accuracy is demonstrated with enriched samples.
