The rising levels of manmade greenhouse gases (GHGs) in the atmosphere and their resulting impact on climate is now one of the single biggest technological and environmental challenges facing the world. This makes intensified monitoring of these gases more critical than ever in order to better quantify the role of the numerous natural and manmade sources, sinks and buffers involved in the cycles of GHGs. It also enables us to objectively audit GHG fluxes at the factory, city, country and continental level. Such objective auditing is ultimately essential to facilitate effective enforcement and compliance with any regulations, laws, treaties and trading agreements based on GHG metrics such as carbon footprints.
LGR analyzers are now widely used for all these purposes. Our comprehensive GHG product line includes our triple GHG analyzer that simultaneously measures carbon dioxide (CO2), methane (CH4) and water vapor (H2O) concentrations, as well as our isotopic carbon dioxide, isotopic water, and isotopic nitrous oxide (N2O) analyzers that measure concentration and stable isotope ratios. These ratios provide vital tracking information that helps quantify the sources and sinks of these important gases. Based on our unique and patented OA-ICOS technology, LGR analyzers provide the ideal combination of small size, low power consumption, high speed (seconds), high sensitivity (ppb), high absolute accuracy, rugged reliability and automated operation required for the most demanding applications. This is why they are so widely used in GHG monitoring applications on all seven continents – for in situ measurement of GHG emissions, as well as for lab measurement of captured air samples, at remote unmanned monitoring stations, at CO2 sequestration sites, and in mobile (truck, airborne) settings. Moreover, the inherent lower cost, and hence higher value, of OA-ICOS is a major benefit to applications which are often budget constrained and often require a network of multiple monitoring sites.
