The Picarro G2201-i isotope analyzer combines capabilities of two Picarro δ¹³C carbon isotope instruments for CO₂ and CH₄ into a single instrument. Now it’s easy and fast to capture the insights that only stable isotope ratios offer. Researchers can follow carbon as it moves from source to sink with a single instrument. The dual-purpose analyzer brings simplicity and speed to research. Its small size and robustness make it easy to transport to the field, where immediate results allow researchers to change course on-the-fly and achieve optimal results from limited-time field campaigns.

• Only field-deployable analyzer for simultaneous high-precision δ¹³C measurements in CO₂ and CH₄
• Three measurement modes: CO₂ only, CH₄ only, and CO₂ and CH₄ combined
• Excellent precision at a fraction of IRMS operating cost—less calibration, less maintenance, no consumables

The analyzer operates in one of three modes: 1) CO₂ only, 2) CH₄ only, and 3) CO₂ and CH₄ combined. In the combined mode, the measurement of CO₂ and CH₄ are interleaved every few seconds to produce a sampling rate that is faster than the gas turn-over time in the cavity. When the analyzer is in CO₂ only mode or CH₄ only mode, the precision improves, because more time is devoted to one molecule. In all modes, the analyzer precisely measures CO₂, H₂O and CH₄ concentrations, with fewer calibration events than other spectral absorption-based instruments. The G2201-i analyzer can be paired with a variety of peripherals to extend and expand functionality.
