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), eddycorrelation

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.
