1.VOC detector product overview

VOC detector can analyze a large number of organic pollutants in the air, such as common VOCs such as benzene series in the air, and ozone precursor analysis.

1.Background and application fields of VOC detector

Volatile organic compounds (VOCs) are important precursors to the formation of secondary pollutants such as fine particulate matter (PM2.5) and ozone (O₃), which in turn cause atmospheric environmental problems such as haze and photochemical smog.With the rapid development of industrialization and urbanization in my country and the continuous growth of energy consumption, the frequency of large-scale simultaneous occurrence of severe air pollution in the region is increasing, which seriously restricts the sustainable development of the social economy and threatens the health of the people.Therefore, in order to fundamentally solve the pollution problems such as PM2.5 and O₃ and effectively improve the quality of the atmospheric environment, the country actively promotes the pollution prevention and control of its key precursor VOCs.In recent years, Beijing-Tianjin-Hebei and surrounding provinces and cities have strengthened the online monitoring of volatile organic compound emissions from key industrial sources, and put forward clear construction requirements for the installation and networking of fixed pollution sources of volatile organic compounds (VOCs) in key industries, online monitoring facilities for unorganized emissions, and excessive alarm sensor devices.

VOCs emission monitoring mainly involves industries such as petrochemicals, organic chemicals, pharmaceutical manufacturing, industrial coatings, machinery manufacturing, packaging and printing, electronic production, synthetic leather, coatings and paints, clothing processing, furniture manufacturing, adhesives, shoemaking, and oil storage and transportation.At the same time, the emission has the characteristics of unorganized fugitives and organized fixed pollution sources, many types of pollutants, large concentration changes, and uncertain emission time.The TVOC automatic monitoring and alarm system can provide real-time contact and provide data on the total amount of TVOC and key monitoring factors of various industries, and connect with the competent departments of the Environmental Protection Bureau online in real time to realize the functions of real-time monitoring of the total amount of TVOC emission reduction and pollution discharge fees.

2.VOC detector monitoring range

The monitoring factors of this product are benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate (TDI), etc.

The product is based on the "Technical Requirements and Detection Methods for Continuous Monitoring System of Volatile Organic Compounds in Ambient Air by Gas Chromatography" (HJ 1010-2018)

"Notice on Strengthening the Monitoring of Volatile Organic Compounds in Waste Gas from Stationary Pollution Sources"
