  • Real-time simultaneous N2O, CO and H2O measurements
  • Sub-ppb precision (N2O, CO) in less than 1 second
  • Measurement rates up to 10 Hz (external pump required)
  • Reports N2O and CO on a dry and wet molar fraction basis
  • No cryogens or water cooling
  • Operational in minutes without training
  • High-resolution absorption spectra are viewable for instrumental diagnostics

The N2O/CO Analyzer uses AGT’s patented String-Topology Absorption Cell. AGT’s technology has many proven advantages over conventional cavity enhan-ced spectroscopy (CRDS & ICOS) techniques, including higher performance, inherent robust-ness, build simplicity and serviceability by anyone, anywhere, anytime. In addition, since AGT’s technology can record reliable absorption spectra over a far wider range compared with all cavity enhanced techniques, AGT Analyzers provide measurements over a much larger range of concentrations and without cross sensitivity.

AGT’s N2O/CO Analyzer is the best instrument capable of continuously measuring ambient levels of nitrous oxide and carbon monoxide with high precision in real time (data rates to 10 Hz with optional external pump). Users can set up the instrument in minutes. Since CO is an excellent tracer of anthropogenic emissions, simultaneous measure-ments of CO and N2O can allow scientists to correlate the sources of N2O emissions. The N2O/CO Analyzer now also simultaneously measures water vapor mole fraction. As a result, the instrument reports N2O and CO on a dry molar basis (accurately corrects for water vapor dilution and absorption line broadening effects) without the need for sample drying or empirical corrections. (For simultaneous high precision measurements of CO and CO2, please refer to AGT’s CO/CO2 Analyzer.)

The N2O/CO Analyzer is designed for many demanding applications including trace-gas (air quality) monitoring (e.g., GAW stations), eddy correlation flux measurements, chamber flux measurements, and combustion diagnostics. The Analyzer is particularly well suited for measurements in the field. The N2O/CO Analyzer is unaffected by other atmospheric gases. Moreover, only AGT’s analyzers provide reliable measurements (guaranteed) at concentrations more than 20 times greater than typical ambient levels and, unlike competitive instruments operating in the near-IR, without cross-sensitivity to hydrocarbons and other gases in ambient air. Furthermore, AGT’s Analyzers report measurements over the widest range of ambient temperatures allowing users to easily record reliable data in the field.

– The N2O/CO Analyzer includes an internal Windows 10 PC that can store data practically indefinitely on its solid state hard drive.
– As with all AGT analyzers, the N2O/CO Analyzer may be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser anywhere.
