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 or changes in atmospheric pressure.


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.


Moreover, only LGR’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, LGR'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 uses LGR’s patented Off-axis ICOS technology, the fourth-generation cavity enhanced absorption technique, which employs a high-finesse optical cavity as the measurement cell. LGR’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell (i.e. precise beam alignment is not critical), LGR Analyzers are relatively inexpensive, simple to build, inherently robust thermally and mechanically, and thus simple to service anywhere by anyone.  In addition, since LGR’s technology can record reliable absorption spectra over a far wider range of optical depths (absorbance values) compared with CRDS, LGR Analyzers provide measurements over a much wider range of gas concentrations and without cross sensitivity to other gases in ambient air. Finally, due to the ease and simplicity of recording and quantifying the measured spectra using LGR’s Off-Axis ICOS, LGR Analyzers display the entire absorption spectra to the user in real time allowing for immediate system diagnostics and performance validation.
