Problems solved by technology
The on-site monitoring instruments of the existing VOCs monitoring system have the following deficiencies: 1. There are many components and related accessories, and the instrument is bulky and heavy; 3. The transportation process needs to be disassembled and loaded again, and it is inconvenient to move. It is often moved up and down, which is time-consuming, labor-intensive and may cause a certain loss to the instrument; 4. The data detected by the monitoring instrument cannot be transmitted to the relevant Departments, unable to achieve accurate and timely data transmission
[0005] In summary, limited by the current online and offline methods, it is difficult to obtain the composition and concentration of VOCs over time at a relatively high time resolution in the existing urban industrial sources, which limits their generation mechanism, safety warning and Research on Related Control Technology

Description
technical field [0001] The invention relates to an online mass spectrometry detection system and method for volatile organic compounds, in particular to an online mass spectrometry detection system and method for volatile organic compounds based on a mobile monitoring vehicle, belonging to the field of detection of volatile organic compounds from urban industrial sources. Background technique [0002] In recent years, the development and progress of human society have met the basic needs of survival, and the problem of atmospheric environmental pollution has gradually attracted widespread attention of human beings. Among various factors that lead to environmental pollution and destruction, volatile organic compounds (Volatile Organic Compounds, VOCs) from industrial organic waste gas have not only become an important source of air pollution, but also become one of the three major killers of air pollution today. one. VOCs are important pollutants that endanger human health. ...
