Applications for Hydrogen(H2) Gas Analyzer
TCD (Thermal Conductivity Detector) technology is another commonly used sensing technology in hydrogen gas analyzers, including those designed for hydrogen gas analysis.
In a TCD-based hydrogen gas analyzer, the principle of operation is based on the thermal conductivity difference between hydrogen and other gases present in the sample. The TCD consists of two temperature-sensitive elements, typically made of platinum or tungsten wire, which are heated to a constant temperature. One element is exposed to the reference gas (usually air or an inert gas), while the other is exposed to the sample gas containing hydrogen.
When the sample gas flows through the TCD, the thermal conductivity of the reference gas remains constant, while the thermal conductivity of the sample gas changes due to the presence of hydrogen. The difference in thermal conductivity between the reference and sample gases causes a temperature imbalance between the two elements of the TCD. This temperature difference is measured and converted into an electrical signal, which is then correlated with the hydrogen concentration in the sample gas.
TCD-based hydrogen gas analyzers offer several advantages:
TCD technology is widely used in various applications where accurate and reliable measurement of hydrogen gas concentrations is required, including hydrogen production, storage, and distribution, fuel cell systems, industrial processes, and hydrogen safety monitoring.
Measuring carbon dioxide (CO2) is important for understanding the role it plays in the environment and its effect on climate change. CO2 is a major component of Earth’s atmosphere, and it traps heat like a blanket, causing global temperatures to rise. Too m uch CO2 can lead to drastic changes in our weather patterns and ecosystems, so monitoring its levels is essential for predicting future climate conditions. Additionally, measuring CO2 can help us better understand our impact on the environment and make informed decisions about how to reduce emissions and slow down down down down down global warming. By analyzing CO2 data over time, we can develop strategies to mitigate the effects of climate change and ensure a sustainable future.
Before industrialization, the global average annual atmospheric carbon dioxide concentration was 278ppm (1ppm is one part per million). In 2012, the global annual average atmospheric carbon dioxide concentration was 393.1ppm. By April 2014 , the monthly average carbon dioxide concentration in the northern hemisphere atmosphere exceeded 400ppm for the first time. . 2. Global climate warming, the continuous aggravation of the atmospheric greenhouse effect leads to global climate warming, resulting in a series of global climate problems that cannot be predicted by today’s science. According to the International Climate Change Economics Report, if human beings maintain the current way of life, by 2100, there will be a 50% chance that the global average temperature will rise by 4°C.
