Nitrous Oxide (N2O)
How can we help you?
Nitrous Oxide (N2O) is a naturally occurring chemical compound composed of an oxygen atom with polar bonds to two nitrogen atoms. It is a significant greenhouse gas responsible for roughly 5% of human emissions (in 2015). Nitrous oxide plays a critical role in the natural nitrogen cycle, formed primarily as a byproduct of terrestrial and oceanic bacterial processes. Atmospheric nitrous oxide may be broken down by other bacteria, UV radiation, or certain chemical reactions.
Atmospheric concentrations of nitrous oxide were stable prior to the industrial revolution. They have since risen dramatically, with 75% of emissions coming from agriculture practices (in 2015), followed by fossil fuel combustion. In these practices, nitrogen is used for enrichment of soils, where biological processes convert it partly into nitrous oxide. Due to agriculture’s vital role in food production, precisely measuring nitrous oxide is an important part of understanding anthropogenic forces on our changing climate.
Picarro has designed and produced several gas concentration analyzers that precisely measure nitrous oxide for laboratory and field studies.
Analyzers
| Product | Measurements | Applications |
|---|---|---|
G2508 Gas Concentration AnalyzerThe 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 AnalyzerThe 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. |

PI5131-i Isotope and Gas Concentration AnalyzerThe Picarro PI5131-i isotopic and gas concentration analyzer enables simultaneous measurements of site-specific and bulk δ15N and δ18O in nitrous oxide (N2O). It is an ideal solution for discerning and measuring the source of N2O emissions through grab-sample measurements in the lab. The isotopomers of N2O can be used to probe sources and sinks in the global nitrogen cycle by identifying nitrification and denitrification processes in soils and water.
The PI5131-i analyzer measures δ15N, δ15Nα, and δ15Nβ with a precision of 0.7 per mil, δ18O with a precision of 0.7 per mil, and N2O concentration with a precision of <0.05 ppb (all precision measurements are at a 10-minute average). |
||
PI5310 Gas Concentration AnalyzerThe Picarro PI5310 gas concentration analyzer provides high-precision measurements of nitrous oxide (N2O) and carbon monoxide (CO) at parts-per-trillion (ppt) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification. The PI5310 is built on the latest Picarro chassis and Linux operating system and includes features to enhance its robustness and ease of use. |
