Carbon dioxide (CO2) is a naturally occurring chemical compound composed of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide is the most significant long-lived greenhouse gas in the Earth’s atmosphere, and is a critical element in the carbon cycle. Natural sources of carbon dioxide emissions include decomposition, ocean release and respiration. Natural sinks of carbon dioxide include photosynthesis by terrestrial plants and absorption by the ocean through physicochemical and biological processes.

The natural exchange of carbon dioxide between air, water, plants and soil remained in balance for thousands of years. But since the Industrial Revolution, anthropogenic emissions—primarily through the burning of fossil fuels and deforestation—have significantly increased the concentration of carbon dioxide in the atmosphere, resulting in global warming. Therefore, precisely measuring carbon dioxide is important to better understand its natural exchange in the environment and the effect of human activity on the carbon cycle and on global warming.

Picarro has designed and produced several gas concentration analyzers that precisely measure carbon dioxide for laboratory and field studies.

Analyzers

Product Measurements Applications

G2131-i Isotope and Gas Concentration Analyzer

The Picarro G2131-i isotope and gas concentration analyer precisely, simultaneously, and continuously measures δ13C in carbon dioxide (CO2) and CO2 and CH4 gas concentration for a range of applications from atmospheric and ocean science research to food and beverage origin and authenticity.

G2201-i Isotopic Analyzer

The Picarro G2201-i isotope analyzer precisely and continuously measures δ13C in carbon dioxide (CO2) and in methane (CH4) to help understand the biological and geological mechanisms that produce and consume CO2.

G2210-i Isotope Analyzer

The Picarro G2210-i isotope analyzer precisely, simultaneously, and continuously measures δ13C in methane (CH4) and the ethane (C2H6) to methane (CH4) ratio for real-time source attribution and quantification of methane emissions.

G2301 Gas Concentration Analyzer

The Picarro G2301 gas concentration analyzer provides simultaneous, precise measurement of carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb) and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.

G2311-f EC Flux Gas Concentration Analyzer

The Picarro G2301-f flux gas concentration analyzer provides simultaneous, precise measurement of carbon dioxide (CO2), methane (CH4), and water (H2O) vapor at 10 Hz for eddy covariance, gradient, and eddy accumulation methodologies.

G2401 Gas Concentration Analyzer

The Picarro G2401 gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.

G2401-m In-flight Gas Concentration Analyzer

The Picarro G2401-m gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification.

G2508 Gas Concentration Analyzer

The Picarro G2508 gas concentration analyzer provides simultaneous, precise measurement of nitrous oxide (N2O), methane (CH4), carbon dioxide (CO2), ammonia (NH3) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for agriculture soil science, ecology, and emissions quantification.

G2509 Gas Concentration Analyzer

The Picarro G2509 gas concentration analyzer is designed for use in livestock farming, manure processing, and fertilizer studies. It provides real-time, at-scale measurements of nitrous oxide (N2O), methane (CH4), carbon dioxide (CO2), ammonia (NH3) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity, with negligible drift.
