Short summary
Tiny variation in natural abundance ratios of stable isotopes of nitrogen and oxygen in nitrous oxide (N2O) can be used as a fingerprint of this trace gas that causes greenhouse effect and stratospheric ozone depletion. Toward the understanding of the global budget of N2O and its temporal change, we developed an automated sample preparation system that can be used to measure the stable isotope ratios in N2O in various air samples collected into flasks with high precision and less labor.
