Abstract

Abstract

Fugitive emission of benzene series and total hydrocarbons has irreversible harm to the ecological environment and human health. The quick and accurate analysis of benzene series and total hydrocarbons has always been a research focus of ambient air monitoring. A quick method for the analysis of total hydrocarbons, methane, benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene and styrene was developed based on the multi-dimensional gas chromatograph with double FID detector. The results show that the target components can be analyzed accurately and quickly in 12 minutes by one injection, and the components show good linearity and repeatability over the measurement range. This method has excellent detection limit and the accuracy ranged from −7.7% to 0.2%. This method can be used for on-line calibration of analytical instruments in different spatiotemporal scenarios, and has potential application value in field navigation monitoring of ambient air.
