Measure atmospheric methane isotopes (δ13C) and ethane-to-methane ratio

The Picarro G2210-i analyzer is designed to address the scientific community’s need for real-time methane emissions source attribution. High-precision atmospheric methane and ethane measurement capabilities, combined with carbon dioxide and water vapor measurements, provide the user with a unique tool to measure and determine the source of methane emissions—including landfills, fracking sites and abandoned oil and gas wells.

  • Simultaneously measures δ13C for CH4 and C2H6-to-CH4 ratio
  • Measures CO2 and H2O vapor, and reports dry mole fractions
  • Field-deployable for real-time CH4 emissions source attribution
  • Small cavity (35 mL) for fast sample turnover time
  • High precision and low drift with outstanding temperature and pressure (T&P) stability

Methane (CH4) is responsible for about 20% of global warming, and about 60% of methane emissions originate from anthropogenic activities. Long-term trend analysis reveals a consistent renewed increase in methane since 2007. The Picarro G2210-i analyzer is ideal for discerning and measuring the source of methane emissions real-time in the field or through grab-sample measurements in the lab.

The Picarro G2210-i analyzer measures δ13C for CH4 at 0.5 – 1.0 0/00 precision, and it measures concentrations of CH4 to less than 0.1 parts-per-billion (ppb) and C2H6 to less than 1 ppb (all precision measurements at a 5-minute average). It also measures CO2 and H2O in dry mole fractions. And it performs all measurements with negligible drift for continuous high-quality data collection. Patented Picarro cavity ring-down spectroscopy (CRDS) technology enables an effective measurement path length of up to 30 kilometers in a compact cavity, which results in exceptional precision and sensitivity from a small-footprint analyzer. A meticulously designed small optical cavity incorporates precise temperature and pressure control. As a result, the analyzer delivers a best-in-class combination of precision, accuracy, low drift and ease-of-use.
