In the "indoor air quality Standard" issued in 2002 of China (GB/T18883-2002), the concept of Total Volatile Organic Compounds (TVOC) is clearly defined, which means all organic compounds with retention time between n-hexane and n-hexadecane when chromatographic analysis is carried out by using a nonpolar chromatographic column. VOCs can be generally classified into eight general categories, based on the differences between their molecular structures: alkanes, alkenes, aromatics, halogenated hydrocarbons, aldehydes, ketones, esters, and others. In view of the serious harm of VOCs, various regulations are issued by various governments in succession, and the emission of VOCs is strictly controlled. The maximum emission concentration of partial VOCs pollutants is definitely and strictly limited by a plurality of regulations issued successively in China, such as the Integrated emission Standard of atmospheric pollutants (GB 16297-1996), the emission Standard of pollutants in petrochemical industry (GB 31571-2015), the environmental air quality Standard (GB 3095-2012) which is implemented from 1 st of 2016, and the like.
