LI-COR Announces the LI-7825 CO2 Isotope Trace Gas Analyzer

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 CO₂ Isotope Trace Gas Analyzer measures CO₂ isotopologues in air and reports CO₂ isotopic ratios with high precision and accuracy. A recent performance evaluation study shows that the LI-7825 meets or exceeds requirements for long-term atmospheric background measurements and offers a versatile platform for a range of applications for a better understanding of CO₂ emissions from anthropogenic and natural sources.

For over 35 years, LI-COR infrared gas analyzers have been used and trusted by researchers and networks around the world. LI-COR Trace Gas Analyzers utilize Optical Feedback Cavity Enhanced Absorption Spectroscopy (OF-CEAS) and multiple patented technologies to perform the measurements. A unique approach to the OF-CEAS method delivers precision and stability to measurements. Because LI-COR Trace Gas Analyzers are designed to be weather resistant and portable, researchers are not limited to indoor or outdoor applications. The lightweight design, long-lasting rechargeable batteries, and optional backpack harness open opportunities for remote research sites, including those at high altitudes.

LI-COR Environmental is a leading technology innovator for plant physiology, ecosystem, soil, light, water, wind, and greenhouse gas research. LI-COR instruments and systems measure the core processes of an ecosystem, from atmospheric gas exchanges with CO₂, CO₂ isotope, CH₄, and N₂O trace gas analyzers and comprehensive eddy covariance systems to complete short and long-term soil gas flux systems. LI-COR provides research solutions for plant and aquatic photosynthesis with the LI-6800 Portable Photosynthesis System, 6800-18 Aquatic Chamber, and LI-600 Porometer/Fluorometer. LI-COR also offers atmospheric and underwater light sensors, leaf area meters, canopy analyzers, sonic anemometers, instrument software, and professional support and training for diverse research initiatives. The LI-COR mission is to impact lives through science, and they strive to help scientists address the challenges facing humanity. For more information, visit our website.
