C2H6 & C2H2
Monitoring of breath gas: C2H6 and C2H2

Medical breath analysis considers ethane and acetelyne as a biomarkers for asthma, schizophrenia or lung cancer. The research field of breath analysis uses methane as a biomarker for intestinal problems.

C2H6
Emission control by methane source identification: C2H6

Ethane is a by-product of methane emissions. The ethane ratio varies between methane emissions from thermogenic and biogenic sources. This allows differentiating oil and gas reserves from those of livestock, landfills, wetlands or stagnant water. Studies are executed on behalf of the US Environmental Protection Agency to quantify methane emissions caused byincreased natural gas exploration and production in the US. A newly developed ethane spectrometer delivers 1 second ethane measurements with sub-ppb precision in an ethane-methane mixture.

[ 61 ]
C2H6
Emission control of greenhouse gases: C2H6

Ethane is an important greenhouse gas that has a critical impact on climate change. Emissions are related to fossil fuel and biofuel consumption, biomass combustion and natural gas losses. Trace gas detection of ethane is an important tool to monitor greenhouse gases.
