[ Focus on Chemical Machinery and Equipment Network ] Recently, some researchers claimed that the global greenhouse gas methane (methane) content and concentration last year reached a high level in history.
The life span of methane is shorter than that of carbon dioxide, which is also a greenhouse gas; but the heat it absorbs is nearly 30 times that of carbon dioxide.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentThe life span of methane is shorter than that of carbon dioxide, which is also a greenhouse gas; but the heat it absorbs is nearly 30 times that of carbon dioxide.
Methane is a hydrocarbon with a simple structure.
It is widely found in natural gas, biogas, and coal mine pit gas.
It is a high-quality gas fuel and an important raw material for the manufacture of synthetic gas and many chemical products.
On the molecular level, methane is a more active greenhouse gas than carbon dioxide, but it is less abundant in the atmosphere.

On the molecular level, methane is a more active greenhouse gas than carbon dioxide, but it is less abundant in the atmosphere.
When the weather gets hot, microorganisms will produce more methane, and hotter weather will breed more microorganisms, thus forming a fatal "climate cycle.
" Given that 2020 is one of the hottest years on record, this could explain the surge in methane.

Subtle changes in temperature and precipitation may increase natural emissions of methane.
This is consistent with the observed isotope signal.
The past practices of reducing greenhouse gas emissions to stabilize the climate have also been challenged and become more complicated.
In 2020, the global methane content will reach a new high, and instruments and meters will help monitor methane.

Measuring methane emissions and leakage is important for many industries (such as agriculture, resource recovery, oil and gas industries), because this gas can cause warming and air pollution.
There are many methods for detecting the concentration of methane in the atmosphere, and gas chromatography is a good choice.
The mobile phase of gas chromatography is a gas, and the transfer speed of the sample is fast.
Therefore, the analysis is relatively fast and the accuracy is high when the methane content is determined.
On the whole, the operation of gas chromatography to determine methane is also less difficult.

In addition, researchers from Princeton University and the US Naval Research Laboratory reported on their new gas sensor , which uses an interband cascaded light emitting device (ICLED) to detect extremely low methane concentrations.
ICLEDs are a new type of high-power light-emitting diodes that emit mid-infrared wavelengths and can be used to measure many chemical substances.
Using its sensor equipment, low-concentration methane gas can be detected, and the cost is very low.

Finally, I want to say that as a greenhouse gas, methane does not stay in the atmosphere for a long time, but its ability to prevent the dissipation of solar heat is far better than carbon dioxide.
And just last week, the British Independent newspaper published a preliminary data collected by the National Oceanic and Atmospheric Administration of the United States, which showed that the concentration of methane in the earth’s atmosphere in 2019 was close to 1875 parts per billion.
Undoubtedly, as far as the greenhouse effect is concerned, the monitoring and control of the concentration of methane in the atmosphere has become one of the important links in the prevention and control of warming, with the help of instrumentation.
