| Abstract: | In this study, an online remote and multi-channel VOC monitoring system is developed. The monitoring system is mainly composed of a remote and multi-channel continuous sampling device and a vacuum ultraviolet single-photon ionization time-of-flight mass spectrometer. The system was characterized by PAMS and organic sulfur standard gases. Results showed that the RSD (n=7) of each substance was less than 7% and the detection limit was 0.004 μmol·mol−1. The linear range was 0.01~1 μmol·mol−1 and the determination coefficient of each substance was greater than 0.99. The quantitative error is between −13% and 25%, which meets the monitoring requirements of VOCs in the environment. By using the monitoring system, analysis of samples from 10 different sampling points can be completed within 1 h; the sampling sites were 500 m away from the monitoring site. On-line analysis of C4~C10 hydrocarbons, organic sulfides and benzene VOCs have been successfully demonstrated. This study has broad application prospects in the monitoring of fugitive emissions of VOCs in chemical parks. |
