The Picarro G2910 Gas Concentration Analyzer for stack and indoor air quality utilizes Cavity Ring Down Spectroscopy (CRDS) to measure ethylene oxide (EtO) at the source. For use with EPA Other Testing Method OTM-47, authored by CleanAir Engineering.

Supporting measurements over a broad range of EtO/EO concentrations, including complex gas mixtures, the G2910 doesn’t sacrifice precision or stability. Accurate, real-time quantification of emissions in stacks, abatement systems, sterilization rooms, aeration warehouses, building ventilation, etc.

Also consider the Picarro G2910 for measuring moisture concentrations from 0–30,000 ppm.

High-quality stainless steel components, an operating temperature of -10-80°C, and a small volume of the critical gas pathway reduces the propensity of acetaldehyde (C₂H₄O) molecules to adsorb onto pathway surfaces, improving the measurement response time (<10 sec) and eliminating measurement biases.

Additional, high-precision measurements of carbon dioxide (CO₂), methane (CH₄), water vapor (H₂O) and other volatile organic compounds (VOC) are used to ensure interference-free operation. The analyzer is housed in a compact form factor that enables fixed or mobile deployments (rack compatible).
