Ethane (C2H6)



Major Applications

nanoplus lasers detect ethane detection in numerous applications, such as emission control as well as breath gas analysis.

Tunable diode laser spectroscopy allows measuring C2H6 with up to ppb precision in real time and in situ. Providing long-term stability and requiring little maintenance, nanoplus lasers are suitable for operation in harsh environments.


Typical wavelengths

Select your target wavelength

nanoplus offers various wavelengths to target the vibrational-rotational bands of water vapour. Select the target wavelength that fits your application best.

The literature recommends several options. They are illustrated in the graphic on the right, which shows the relative intensities of the possible absorption lines. To define the most suitable C2H6 wavelength for your application, you may have a look at our literature recommendations below or refer to the HITRAN database from the Smithsonian Institute.

We present the most common Distributed Feedback lasers for C2H6 detection below. Learn more about their specifications.

Factors which you should consider in your setup

Above wavelengths as well as further customized wavelengths for ethane detection are available from nanoplus.

When you choose your wavelength, you have to consider your product set up, environment and nature of the measurement.

These factors influence the optimum wavelength for your application. Do have a look at the Hitran Database to further evaluate your choice of wavelengths. Our application experts are equally happy to discuss with you the most suitable wavelength for your application.

Let us know the wavelength you require with an accuracy of 0.1 nm!

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.

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.

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.
