Air Quality

Air quality science looks at the degree to which the ambient air contains pollution. There are several factors that can affect air quality, both natural—such as from volcanic eruptions or dust—as well as human-induced. Significant outdoor sources of anthropogenic air pollution include carbon dioxide (CO₂) from vehicles and aircraft, as well as methane (CH₄) and ammonia (NH₃) from raising livestock. Indoor sources include formaldehyde (H₂CO) from household products and carbon monoxide (CO) from gas stoves. Air quality monitoring networks include satellites, airborne sampling, and ground methods.

G2910 Gas Concentration Analyzer Within Picarro’s family of Ethylene Oxide (EtO) gas concentration analyzers, the G2910 Stack and Indoor Air Quality Analyzer has been configured to enable measurements of EtO at the source of emission. The G2910 supports measurements over a broad range of EtO concentrations, with support for complex gas mixtures, without sacrificing precision and stability. In applications where accurate, real-time quantification of EtO emissions is required, Picarro excels over traditional technologies, such as Fourier-Transform Infrared Spectroscopy (FTIR) or Gas Chromatography (GC). Quantification of EtO from stacks, abatement systems, sterilization rooms, aeration warehouses and building ventilation has never been easier.	G2910	Ethylene Oxide (C₂H₄O)
G2920 Gas Concentration Analyzer Within Picarro’s family of Ethylene Oxide (EtO) gas concentration analyzers, the G2920 Ambient Analyzer introduces a platform that supports long-term monitoring of fugitive emissions at the fenceline and ambient concentrations of EtO near communities. In applications where accurate, real-time quantification of EtO emissions is required, Picarro excels over traditional technologies, such as Fourier-Transform Infrared Spectroscopy (FTIR) or Gas Chromatography (GC). Quantification of fugitive EtO emissions from industrial facilities has never been easier.	G2920	Ethylene Oxide (C₂H₄O)
G5310 Gas Concentration Analyzer The Picarro G5310 gas concentration analyzer provides simultaneous, precise measurement of nitrous oxide (N2O), carbon monoxide (CO) at parts-per-trillion (ppt), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.
