The LI-7820 N2O/H2O Trace Gas Analyzer offers high-precision nitrous oxide measurements in a low power, portable design—enabling it to easily integrate into survey and long-term soil flux systems. Pair it with the LI-7810 CH4/CO2/H2O Trace Gas Analyzer or LI-870 CO2/H2O Analyzer for CO2 and CH4 measurements at your site.
A combination of several patented technologies with Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS) results in precise and stable N2O measurements, for chamber-based soil flux research.Get a Quote
Measuring N2O and Other Trace Gases in Soil and Air Using LI-COR Trace Gas Analyzers
From soil flux measurements of N2O and CH4, to point-source detection systems, LI-COR Trace Gas Analyzers are the new standard for portable, precise gas measurements.Watch the recording

Designed for soil flux measurements, the LI-7820 N2O/H2O Trace Gas Analyzer brings the precision you need to measure both natural variation in fluxes and large flux events, even in remote areas. With the ability to resolve fluxes quickly, you can take more measurements throughout the day and quickly visualize those fluxes with SoilFluxPro™ Software.
N2O flux measurements from soil are often minimal and close to zero. Natural variation still occurs, however, and is important to quantify. A highly precise analyzer that can quickly resolve small fluxes is essential for detecting minute, natural variations in soil N2O flux. The LI-7820 allows you to take precise measurements of these slight variations and to resolve natural N2O fluxes in addition to measuring large fluxes, such as changes that occur after a fertilizer treatment.
The example given is from a LI-COR long-term soil flux system. The LI-7820 was used to measure larger fluxes emitted during spring thaw events in Lincoln, Nebraska, while also recording smaller natural fluxes. Figure 2 provides an example flux calculated in 2 minutes from a closed-chamber measurement.
