Paper Abstract

This work presents our recent progress in development of a field-deployable isotopic N2O analyzer based on mid-infrared cavity ring-down spectroscopy technique. This instrument operates using thermoelectrically cooled technology, enabling the system to be run unattended for extended periods of time without the use of liquid nitrogen. Ambient atmospheric gas samples are introduced directly into the instrument which will be capable of measuring N2O concentration with precision of 0.1 ppb in less than a minute of data acquisition time, while isotopic ratio of 15N/14N of N2O is analyzed at < 1 ‰ precision within a few minutes.
