VOCs is a general term of a series of volatile organic compounds, which is an important air pollutant. When it exists in the air, it will produce chemical reactions to produce secondary aerosols (SOA) and other fine particles, as well as the chemical pollution caused by ozone. Sy-voc900 and sy-gc8000 VOC on-line monitoring systems are designed and developed according to the function, structure, performance, installation and test required in HJ 38-2017 standard of national determination of total hydrocarbon, methane and non methane total hydrocarbon in waste gas from fixed pollution sources!
It can measure non methane hydrocarbon, benzene series, alcohol, ketone, aldehyde, etc
