Monitoring of 120 VOCs on Site Without Risk of Contamination

Chromatotec (France) is continuously developing new applications with one common objective: providing automatic field expertise and sensitive solutions.

The last application sold for industrial area in Shanghai was designed for the continuous monitoring of more than 120 Volatile Organic Compounds (VOCs) with auto GC 866 FID/MS (airmoSCAN XPERT). This system is totally designed for automatic online monitoring in fixed or mobile station and can be implemented on site. This plug and play solution includes a calibration system based on the principle of permeation tubes. This allows an automatic validation of data directly on site without human intervention.

The huge advantage of this solution is the avoidance of onsite sampling with contamination risk of the sample during transportation as VOCs are highly reactive. The airmoSCAN XPERT requires only power supply as fuel gases (zero air and hydrogen) are produced by generators and calibration is done by internal permeation tube for daily automatic data validation. This solution can be easily implemented near industrial sites where an important quantity of compounds can be emitted and can be found in ambient air. This global solution offers double check measurement to ensure accurate identification in spite of possible coelution effects. To get a complete finger print of the area, it is also possible to add to this complete and scalable solution an analyser dedicated to the measurement of Total HydroCarbons and an analyser for the measurement of sulphur compounds.
