nanoplus lasers detect methane detection in numerous applications, such as in combustion control, detection of greenhouse gases, breath gas analysis as well as in leakage control in gas pipelines.
Tunable diode laser spectroscopy allows measuring CH4 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.
nanoplus offers various wavelengths to target the vibrational-rotational bands of methane. 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 CH4 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 CH4 detection below. Learn more about their specifications.
Above wavelengths as well as further customized wavelengths for methane 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!
We compiled several papers on methane detection based on tunable diode laser absorption spectroscopy. Refer to below literature list to read more or select your paper by application.
Greenhouse gas effects and climate change have triggered global emission monitoring of pollutants like methane. Methane is one of the Earth’s most important atmospheric gases. It is, to a large extend, responsible for the accelerating greenhouse effect. The global warming potential of methane is about 30 times higher than that of CO2 based on a 100 year scale. Studies are executed on behalf of the US Environmental Protection Agency to quantify the methane emissions caused by the increased natural gas exploration and production in the US.[ 176 , 162 , 146 , 142 , 141 , 129 , 128 , 119 , 109 , 107 , 92 , 61 ]
Leaks of CH4 may cause dangerous situations and are hard to locate precisely. Hence, maintenance of underground pipelines produces high costs. CH4 leaks are also an important source for greenhouse gases. With TDLAS a strong tool is available to manufacture portable leak detectors.[ 162 ]
Methane content of syngas is controlled to improve combustion efficiency of integrated gasification fuel cell cycles.[ 35 ]
Continuous monitoring of contents like CO2 or CH4 concentrations is essential for the efficiency of high-temperature processes in e. g. incinerators, furnaces or petrochemical refineries. Managing the CO2 content in combustion processes simultaneously reduces greenhouse gas emissions. This is also relevant for energy generating industries like coal burning power plants.[ 154 , 124 , 121 , 115 , 112 , 111 , 96 , 94 , 62 , 45 , 40 , 35 , 12 ]
