LI-7825 high-precision CO₂Isotope analyzer measures the four most abundant CO in the atmosphere₂Gas isotope isomers obtained containing δ¹³C、δ¹⁷O and δ¹⁸Accurate data of O gas. Measure CO₂Gas isotope isomers and their ratios can be calculated for the following studies:

Identify sources and sinks of carbon in the atmosphere

● Distinguish net ecosystem carbon exchange

● Gain a deep understanding of biological processes

● Evaluate carbon sequestration work

LI-7825 is a new member of the LI-COR trace gas analyzer series, based on LI-COR's 35 years of experience in greenhouse gas monitoring research and production. During testing, it has consistently gained the trust of researchers in the industry.
