Picarro analyzers, specifically the G2210-i, are used to measure both methane isotopes (δ¹³C) and the ethane-to-methane ratio (C₂H₆/CH₄).These measurements are crucial for identifying and quantifying methane emission sources. The δ¹³C value helps differentiate between biogenic and thermogenic sources of methane, while the C₂H₆/CH₄ ratio is particularly useful in distinguishing between natural gas and biological sources.
