N₂O/CO Analyzer (Nitrous Oxide, Carbon Monoxide) Datasheet

LGR’s N₂O/CO Analyzer is the first 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 measurements 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 mol 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 LGR’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 and has been successfully deployed on-board aircraft for measurements in the upper troposphere / lower stratosphere. The N₂O/CO Analyzer is unaffected by other atmospheric gases.

The N₂O/CO Analyzer is available in different packages to serve customers’ requirements. For measurements with highest precision and stability, LGR’s “Enhanced Performance” packaging incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy, linearity, stability and drift. For field studies or other applications requiring portability (e.g., flux chambers), the N₂O/CO Analyzer is now available in LGR’s aclaimed ultraportable package.
