LI-COR Inc., a global leader in environmental measurement technology, announced its forthcoming LI-7825 CO₂ Isotope Trace Gas Analyzer, which will measure CO₂ isotopes in the lab, in the field, and on the move.

LINCOLN, Neb., Nov. 16, 2022 /PRNewswire/ -- CO₂ isotope measurements are a critical tool for studying climate change and for modelling future climate scenarios. By measuring CO₂ isotopes and calculating isotopic ratios, researchers can identify the sources and sinks of atmospheric CO₂, evaluate carbon sequestration efforts, partition net ecosystem carbon exchange, and gain insights into biological processes.

The LI-7825 Isotope Trace Gas Analyzer will measure CO2 isotopes in the lab, in the field, and on the move.

The LI-7825 CO₂ Isotope Trace Gas Analyzer measures ¹²C-CO₂, ¹³C-CO₂, ¹⁸O-CO₂, ¹⁷O-CO₂, and H₂O in air and reports CO₂ isotopic ratios—δ¹³C, δ¹⁸O, and δ¹⁷O—with high precision and accuracy. It utilizes Optical Feedback‑Cavity Enhanced Absorption Spectroscopy (OF-CEAS) and several patented technologies to perform the measurements.

"The LI-7825 δ¹³C CO₂ precision of 0.1 per mille is competitive with laboratory laser-based analyzers but comes in a portable and field-ready form factor," said Mark Johnson, Vice President of Research and Development. "Its performance combined with the ability to measure δ¹⁷O and δ¹⁸O isotopic ratios of CO₂ will enable research in novel applications and unique environments."

Backed by over thirty-five years of experience in gas analysis technology, the LI-7825 joins the LI-COR Trace Gas Analyzers used and trusted by researchers and networks around the world. LI-COR expects to ship the LI-7825 in mid to late 2023.

LI-COR is an industry-leading environmental technology innovator of high-quality instrument systems for eddy covariance, plant physiology, soil gas flux, light, gas analysis, and greenhouse gas research. LI-COR instruments and systems are used by networks and researchers around the world.
