Overview
About LI-7825 CO2 Isotope/NH3 Trace Gas Analyzer
Measure the four most abundant CO2 gas isotopologues with high precision and accuracy in a portable analyzer that fits in a backpack. Designed for mobile monitoring and integration into soil gas flux systems, the LI-7825 enables researchers to explore new questions with confidence.
Backed by over thirty-five years of experience in gas analysis technology, the LI-7825 joins the LI-COR Trace Gas Analyzers trusted by researchers and networks around the world. The platform uses Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS) paired with patented technologies and innovations to provide a stable analyzer that requires little user maintenance and no factory calibrations — all at a more affordable price than previously available for isotopic measurements.
The LI-7825 integrates with LI-COR's renowned LI-8250 Multiplexer Soil Gas Flux Systems to take continuous CO2 isotope measurements in the field, enabling real-time Keeling-based soil δ13C estimates and on-site calibration.
