Online monitoring system for volatile organic compounds in ambient air

Ontech700Online monitoring system for volatile organic compounds in ambient airIt is a detection system developed for the air quality of factories, plant areas, and urban environments. The system can accurately monitor the content of non methane total hydrocarbons, benzene derivatives, and special factors.

The system adopts an online chromatograph independently developed by Antech, which can integrate a high-efficiency enrichment secondary cold trap, use high-precision mass flow meters, and desorption analysis technology. It has ultra-high sensitivity and can meet the needs of Factory boundary, factory area, and city Low or even trace levels of ambient airMonitoring of VOCs. The entire system combines meteorological parameters to form a report on the upper computer of the monitoring system, which is uploaded to the environmental protection platform through a data acquisition instrument using the standard HJ 212 protocol to meet the monitoring requirements of the environmental supervision department. At the same time, the data can be transmitted to the DCS system of the park or factory area, which facilitates real-time monitoring of concentration at various monitoring points in the factory area by the central control room. It can achieve functions such as SMS notification of equipment failure information and over limit alarm information, login and operation records, automatic multi-point calibration, gas under pressure and liquid shortage alarm. Integrating security design, automated monitoring, intelligent supervision, and fast and timely alarm.
