CEMS conducts continuous online monitoring of the flue gas generated in the industrial production process. Smoke is a large category with very complex composition, which includes not only gas components harmful to the human body, but also solid components contained in the gas that are harmful to the human body, which is what we often call particulate matter.

Particulate matter is also called soot and dust. Its composition is very complex, including particulate matter of various metals, non-metal oxides, various salts and various organic compounds, which cause serious pollution to the environment and serious harm to the human body.
Particles with a particle size of less than 10μm are called inhalable particles. Long-term inhalation of toxic fumes can cause poisoning. For example, fumes containing free silica can easily cause pneumoconiosis. Long-term inhalation of manganese dust can cause toxic pneumonia, and long-term inhalation of adhesion3, The particles of 4-benzopyrene can cause lung cancer. In particular, particles with a particle size between 0.5 and 5 μm are easy to enter the lungs and deposit, and may enter the blood and reach the whole body, leading to cardiovascular disease.

Smoke and dust are the primary pollutants that affect ambient air quality. They are one of the key pollutants that my country implements total control, especially the particulate matter emitted by fixed pollution sources. Therefore, in the online flue gas monitoring system, the online monitoring of particulate matter is very important a part of.
