Picarro Cavity Ring-Down Spectroscopy Analyzer for Isotopic N2O - Concentration and Isotopes

A Truly Field Deployable, Continuously Measuring N₂O Isotope Analyzer - G5101-i 

• N₂O concentration and isotopes

• High precision at atmospheric concentrations

• δ¹⁵N measurements including site specific isotopomers

• Cryogen-free operation

• Field and laboratory deployable

Interested in seeing data from this system? This analyzer is being tested in the labs at Picarro and with a select group of research partners. We will continue to post updates and results from these tests showing actual analyzer performance in the Picarro Community.

APPLICATIONS

This system can be used to determine terrestrial sources and sinks of N₂O for improving predictive models and better understanding of the human contribution to global warming. In addition, scientists can also use this system to gain valuable information on nitrification and denitrification processes in soils and water through site specific and bulk δ¹⁵N  measurements.

CAPABILITY

Capable of field station or lab use, the G5101-i measures ambient level N₂O concentration and δ¹⁵N isotopes including the site specific isotopomers δ¹⁵N^α and δ¹⁵N^β with precision better than 0.05‰.

TECHNOLOGY

This analyzer uses newly available room-temperature mid-IR sources and detectors coupled with Picarro's proven wavelength monitor and unique time-based Cavity Ring-Down Spectroscopy (CRDS) designs. With an effective path length of up to 8 km, and the increased molecular absorption in the mid-IR, the sensitivity and precision of this instrument is unmatched by traditional absorption and ICOS based systems. Further, our patented wavelength monitor makes certain that only Picarro can operate with low drift performance.
