Environmental pollution has become a worldwide problem. Rapid industrialization and urbanization have led to a serious decline in air, water and soil quality. Industrial emissions are the main source of air pollutants worldwide. It is particularly important to optimize processes and control pollutant emissions. In order to cope with severe environmental challenges, regulatory agencies around the world have set strict emission limits for different types of pollutants. Environmental regulations require continuous 24-hour emission monitoring of all industrial facilities.The rise of man-made greenhouse gas content in the atmosphere and its impact on climate is also one of the important environmental challenges facing the world today. Global climate change is mainly caused by the massive accumulation of greenhouse gases such as CO2, CH4 and N2O in the atmosphere. Therefore, it is necessary to strengthen the monitoring of these gases, distinguish greenhouse gases from different sources, and carry out targeted emission optimization and control.In the past few years, air pollution has also become a major global challenge. Air pollution causes millions of deaths around the world and damages the world economy by 5 trillion dollars every year. More than 90% of the world's population lives in areas where air quality exceeds WHO standards. Both human activities and natural processes produce air pollution, such as transportation, energy production, manufacturing and chemical industries, landfills, forest fires and volcanic activities. Therefore, air quality monitoring is very important for the government and industrial departments to monitor the impact of air pollution on the environment.VOLSENSING SENSOR & ANALYSZER SUITABLE FOR ENVIRONMENT APPLICATIONThe gas sensors & analyzer provided by VOLSENSING based on LAS, CLD, PAS, FTIR and other principles can be widely used in various applications of environmental gas detection.Laser Absorption Spectroscopy gas sensor (LAS) is based on quantum cascade laser (QCL) technology.

With the increasing number of motor vehicles, motor vehicle pollution has become a major chronic disease of environmental pollution. In order to alleviate the air pollution caused by motor vehicle emissions, countries all over the world are competing to develop new energy vehicles in recent years. Although new energy vehicles have made great progress, the application of internal combustion engines using gasoline and diesel as fuel still occupies a dominant position at this stage. Therefore, how to effectively control automobile pollution is still a global concern and urgent problem to be solved.In order to protect the environment, various environmental regulations and standards for motor vehicle emission pollution have been issued worldwide. At present, the vehicle emission standards formulated by various countries in the world are mainly divided into three systems: European emission regulations, American emission regulations and Japanese emission regulations. European standards are jointly implemented by the automotive exhaust emission regulations of the Economic Commission for Europe (ECE) and the automotive exhaust emission directives of the European Union (EU). The automobile emission regulations in the United States can be divided into federal emission regulations, namely, the Environmental Protection Agency (EPA) emission regulations and the California Air Resources Board (CARB) emission regulations, and other states can choose to use California regulations or federal regulations according to their own needs; Japanese regulations began to be implemented in the late 1980s. In 2005, Japan began to implement new vehicle emission standards, and the emission limits were much stricter than before.The development of automobile engine and the research of new emission control technology are inseparable from automobile emission detection system. The correct detection of the content of harmful automotive emissions is an important prerequisite for the study of the formation of harmful automotive emissions and its control technology and devices. With the increasingly stringent automotive emission standards in various countries, the engine laboratory emission detection system, portable emission detection system (PEMS), deNOx, exhaust emission detection and other related detection technologies in the SCR application of diesel engine development have been continuously improved, and a variety of gas sensing technologies have also been applied. It is usually necessary to detect a variety of pollutants including CO, CO2, THC, NOx, NO2 and NH3.VOLSENSING SENSOR & ANALYSZER SUITABLE FOR AUTOMOTIVE APPLICATIONThe gas sensors & analyzer provided by VOLSENSING based on LAS, CLD, PAS, FTIR and other principles can be widely used in various automotive gas detection applications.Laser Absorption Spectroscopy gas sensor (LAS) is based on quantum cascade laser (QCL) technology.

Industry is the basic power to promote the development of human society, and it also promotes the development of productive forces. However, many problems have to attract people's attention, and environmental problems are one of them. In the process of industrial production, various waste gases, waste water and waste residues will be produced. The discharge of these industrial production wastes into the natural environment will undoubtedly cause harm to the environment, among which the discharge and impact of industrial waste gases are the largest. Exhaust gas discharged into the air will flow and diffuse with the atmosphere, threatening people's health. Therefore, the treatment and detection of industrial waste gas has become a problem that must be paid attention to in modern industrial production.In the industrial production process, relevant process control technologies are usually used to optimize the production process, improve production efficiency, or reduce industrial exhaust emissions. For example, the selective catalytic reduction/DeNOx process (SCR/DeNOx) aims to reduce the emission of nitrogen oxides. Nitrogen oxides are toxic and harmful environmental pollutants, which are formed when fuel is burned at high temperatures. At present, many government environmental protection departments have strictly stipulated the emission limits of nitrogen oxides. The selective catalytic reduction process uses urea (NH3) to convert nitrogen oxides into N2 and H2O, thus reducing the emission of nitrogen oxides. It is one of the most popular technologies to reduce NOx emissions. It is mainly used in coal-fired power plants, steel plants, diesel engines, marine engines, etcNatural gas pipeline is one of the important signs of industrial modernization. Due to the inherent high-pressure, flammable and explosive characteristics of natural gas pipeline transportation, pipeline safety management is extremely important. Natural gas leakage is one of the most important security threats in pipeline operation, and it is easy to spread, often causing serious accidents such as fire and explosion. Therefore, fast, accurate and convenient CH4 gas leak detection technology is particularly important.VOLSENSING SENSOR & ANALYSZER SUITABLE FOR INDUSTRY APPLICATIONThe gas sensors & analyzer provided by VOLSENSING based on LAS, CLD, PAS, FTIR and other principles can be widely used in various industrial gas detection applications.Laser Absorption Spectroscopy gas sensor (LAS) is based on quantum cascade laser (QCL) technology.
