Methane (CH4)

Methane

Methane (CH4) is a naturally occurring compound composed of one carbon atom with single covalent bonds to four hydrogen atoms. While it has a shorter lifespan than carbon dioxide (CO2), it bears an outsized impact on climate change with about 85 times the Global Warming Potential over a 20-year period. Natural sources include wetlands, volcanoes, and wildfires, while interactions in both soil and the atmosphere can help break methane down.

Methane concentrations have remained steady for thousands of years. However, industrial revolution, population increase, and subsequent rise in livestock farming have led to unprecedented methane concentration levels. As methane-releasing industries are significant drivers of climate change, measuring methane is important to better understand and mitigate human impact on the environment.

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

Closed System Measurements

Whether you are looking at gas evolution from soils or vegetation, or the incorporation of stable labels into living organisms, our rugged, high-precision analyzers offer unparalleled performance. Picarro’s small cavity design technology has long been the optimal choice for sample-limited studies. Now we have developed a series of turn-key systems especially designed to avoid external contamination.
