Methane Gas Analyzer

The National Oceanic and Atmospheric Administration (NOAA) is seeking a commercial methane gas analyzer. The analyzer should be similar to the Aeris Technologies MIRA Ultra, with features such as mid-infrared absorption technology, high-precision measurement capability, and near real-time automated data transmission. The device should be portable, lightweight, and compatible with a Nafion dryer, external pump, and flow control. The delivery location is Boulder, CO, and the delivery time is 60 days after receipt of the order. • The analyzer should utilize mid-infrared absorption (MIRA) technology for trace gas monitoring. • It should have a highly portable, lightweight form factor suitable for benchtop, mobile laboratory, tower, or drone/aircraft deployments. • The analyzer should have high-precision, parts-per-billion (ppb) measurement capability for Methane (CH4) and Ethane (C2H6) dry mole fractions to distinguish between biogenic and thermogenic sources. • It should include or seamlessly integrate with a Nafion dryer (for moisture correction), external pump, and flow control. • The analyzer should have near real-time automated data transmission capabilities. • The measurement precision should be 1 ppb for CH4 in one second at approximately 2000 ppb CH4. • The data output should be available via ethernet port or USB connection. • The size of the optical component (temperature-controlled cell and detector) should be no larger than 7” x 8” x 5” (not including associated electronics and gas handling components). • The power consumption should be less than 25W at steady state. • The analyzer should be compatible in size, power, and electrical and data connections with the Aeris MIRA Ultra portable gas analyzer.
