本应用说明概述了 Picarro G2201-i 双碳(CO2 和 CH4)同位素分析仪的配置和使用,用于区分瑞典南部过渡农业实验中的 C3 和 C4 呼吸源
漫灌的农田土壤是二氧化碳(CO2)、甲烷(CH4)和氧化亚氮 (N2O)等温室气体(GHG)的重要来源(Linquist 等人,2011;Oertel 等人,2016)。由于这些生态系统具有高度的时空异质性,因此需要连续测定痕量气体浓度,以便更好地监测其排放模式和量化净生态系统通量。在漫灌期间,测量地表通量是一项具有挑战性的工作,但是错过这些时期,可能会显著地低估每年的 CH4 排放量,并有可能高估 N2O 的排放量。本文我们通过对 Eosense eosAC 自动化呼吸室系统进行改造,并将 Picarro G2508 温室气体分析仪置于改造过的 Bonar 塑料保温箱中,对定期漫灌田地进行了连续测定。…
新型G2509分析仪在高浓度甲烷环境中实时测量氨气、二氧化碳、甲烷、一氧化二氮和水蒸气的排放。
加州圣克拉拉--2022年4月13日-- 气体分析领导者Picarro 公司宣布推出G2509气体分析仪,该分析仪可以使企业准确量化其氨和温室气体(GHG)的排放。化肥厂、牲畜养殖场、粪肥处理设施,以及农业领域的许多其他设施,都是氨和温室气体的重要排放源。量化和报告他们的直接排放是改善空气质量和农业实践脱碳的关键第一步,可以减少农业对环境的影响。通过部署G2509分析仪,农民能够提供准确的空气质量和气候信息,并制定缓解措施,这都是农业经济部门健全的环境、…
In January, Picarro introduced a first-of-its-kind solution for natural gas pipeline leak detection and measurement, based on our new series of methane isotope analyzers. The new solution, called the Picarro Surveyor™ for Natural Gas Leaks, measures methane plumes in the air, maps them, and then immediately alerts users and repair teams upon leak detection in real-time while traveling at…
One mustn’t look too far to find a story about natural gas production - whether from the perspective that it will transform the global economy or drive the climate past the point of no return. Whether you’re for gas or against it, the only chance we have to make clearheaded decisions about the issue is through credible measurements and complete transparency.
Without question, the…
Natural gas will not live up to its promise without the vital support of a society focused on transparency.

Emissions of methane (CH4) from oil and natural gas (O&G) operations in the most densely drilled area of the Denver-Julesburg Basin in Weld County located in northeastern Colorado are estimated for 2 days in May 2012 using aircraft-based CH4 observations and planetary boundary layer height and ground-based wind profile measurements. Total top-down CH4…
Production of natural gas from shale formations is bringing drilling and production operations to regions of the United States that have seen little or no similar activity in the past, which has generated considerable interest in potential environmental impacts. This study focused on the Barnett Shale Fort Worth Basin in Texas, which saw the number of gas-producing wells…
We present a study of methane emissions from oil and gas producing well pad facilities in the Barnett Shale region of Texas, measured using an innovative ground-based mobile flux plane (MFP) measurement system, as part of the Barnett Coordinated Campaign.
